I n t r o d u c t i o n

We ought to view all monotheistic religions (religions which enjoin belief in one God) in the spirit in which St. Peter viewed them when he said, "Of a truth I perceive that God is no respecter of persons, but in every nation he that feareth Him and worketh righteousness is accepted with Him." [Acts10:34,35]

The same is the spirit of the oft-repeated definition of "Muslims" in the Qur'an: "Those who believe and work righteousness" (al-lazina amanu wa amalu-s-salehat) [Qur'an 2:25, 2:62, 2:25 etc.]. And "Trust in the Lord and do good," as the Psalms say. [Psalms 37:3]

It is essential that any discussion of Islam as a monolithic religion must begin with its very fundamental concept of unity of God (Tawhid). In this context, it is also important to note that the creed of Islam is very simple. To become a Muslim, one has only to declare in sincerity, and preferably in the presence of a person already professing Islam, "I testify that there is none worthy of worship (god) but God, and that Muhammad is the Prophet of God". The first part of the Muslim creed is a dialectically rigorous rejection of polytheism in favour of monotheism. It underlies the pivotal Muslim doctrine of divine unity (Tawhid), and has historical antecedents in both Judaism and Christianity.

The first part of the creed presupposes a cosmology that includes an invisible as well as a visible world. Underlying the cosmology of this first part of the creed, which is universalistic and acknowledged by all monotheistic faiths, is a concept of prophesy which is particularized and, by demanding recognition of Muhammad as God's Prophet becomes unacceptable to non-Muslims. None of the teachings of prophets who preceded Muhammad are denied. From Adam and Abraham to Solomon and Jesus, the Biblical and even extra-Biblical prophets are affirmed, many of their actions and utterances being lauded in the pages of the Qur'an. For this reason Muslims do not subscribe to the Jewish view which according to Jewish tradition asserts that prophecy ceased about 400 B.C. so that there could be no new scriptures after that time.

Christians maintain, on the contrary, that prophecy continued and that the writings that eventually became the New Testament were also divinely inspired. But since Muslims maintain and believe that Muhammad is also the last prophet, the revelations communicated through him supersede, even as they mark the culmination of all earlier SCRIPTURES. The authority of both, Jewish and Christian scriptures is subordinated to the content of Muslim revelation, and the former serve as a theological, not merely a chronological, preamble to Islam.

It is a well known fact that there is no trace today of the scrolls of Abraham. We are also aware of the sad story of the Torah of Moses and how it was destroyed by Pagans several times. The same fate befell the Psalter. As for Jesus, he had not had the time to compile or dictate what he preached. It was his disciples and their successors who gleaned his utterances and transmitted them to posterity in a number of recensions [a critical revision of the text], of which at least 70 recensions of the Gospels are known, and with the exception of four, all are declared by the Church to be apocryphal.

For such reasons, both the Torah and the Gospels are regarded as corrupted (Arabic term Tahrif, which means altering the words or misrepresenting the meaning) in their present form. Consequently, in these earlier revelations, whatever disagrees with the Qur'an is abrogated by the Qur'an.

Our presentation of some remarkable points of similarities and differences (set out in chart-form below) is meant to demonstrate and illustrate (as examples of practical application) how this principle of abrogation permeates not only the whole spectrum of Islamic teachings based on the Qur'an and the Traditions of Prophet Muhammad in general, but also underlies the whole Islamic legal system (Shar'iah and Fiqh). It is because of such application of this principle of abrogation that the Qur'an retells many stories found in the Hebrew Bible and the New Testament. No doubt the majority of Muslims, therefore, acquire their knowledge of the Bible solely from the Qur'an. Nevertheless, many Muslims have studied and several novelized lives of Jesus have been published in the twentieth century, especially in Egypt.

The Muslim position on this issue is twofold:

a) that the injil [Arabic for 'Bible'] like the Qur'an, was a real Scripture -- the original Word of God, sent down from the heavens and transmitted to the human Messenger (Prophet) Jesus on earth, through the medium of the celestial messenger (the angel Gabriel), as the highest form of infallible divine inspiration called wahy in Arabic.  Christians have lost their injil, whereas Muslims have managed to meticulously preserve every word of their Qur'an in its original purity. [For further information please see The Preservation of the Original Teachings of Islam] [Also Click here to view two articles by Maulana Mohammad Aleem Siddiqui about how the Qur'an and the Prophetic Traditions were arranged and compiled.]
    God is transcendent and beyond all the physical perceptions of man and also above all the limitations and bounds of language. The Scriptures have been revealed to the Prophets in different languages and at different times according to the needs and circumstances of those times. The phenomenon of Divine Guidance may be explained by using the following metaphor that "the Prophets are like lightbulbs and revelation is the electric current -- when the current contacts the light bulb, the light bulb provides light according to its voltage and colour. The mother-tongue of a Prophet is the colour of the light bulb, whereas the power of the light bulb, (i.e., the current and other things) are determined by God Himself. The human factor then, is just an instrument of transmission and only an intermediary." [Dr. Hamidullah, Introduction to Islam]

b) that not only the Prophet Muhammad's p.b.u.h. own words, sayings or utterances, as distinct from God's Words (the Qur'an) but also a record of his actions and tacit approvals, have all been separately preserved. They are known as Hadith, Traditions, or Sunnah. Muslim scholars  maintain that The New Testament, which contains the writings of the disciples of Jesus are really more like the Hadith of the Prophet Muhammad, p.b.u.h., whereas the injil, which has been lost, was like the Qur'an. Accordingly, since the Qur'an has remained unaltered to the present day, (compared to the other Scriptures) Muslims assert that only the Qur'an contains the Words of God -- the truth in toto (i.e., the whole truth and nothing but the truth). Whereas the earlier Scriptures/Books such as The New Testament, The Old Testament, etc. contain only partial truths (i.e., much less than the whole truth).

Consequently, in this connection, the scholars of Islam always seem so intent on bringing home the universal truth relating to change and renewal. It is maintained that this principle of change, revision, and renewal is enshrined in the laws of Nature itself and that such laws permeate the whole Divine Scheme of Guidance. This universal law has been beautifully articulated by Lord Alfred Tennyson in these serene and sombre yet simple words:
The old order changeth, yielding place to new,
And God fulfils Himself in many ways
Finally, the principle of abrogation does NOT mean nor does it operate by seeking the absorption and assimilation of everyone such as Christians, Jews, or other minority groups into the "ruling" Muslim community. Islam protects the interests of all its subjects. Islam welcomes and even encourages every group, Christian, Jewish, Magian or other to have its own tribunals presided over by its own judges, in order to have its own laws applied in all branches of human affairs, civil as well as criminal. This is a characteristic feature of the Quranic legislation which accords judicial autonomy to different minority communities living under the Muslim rule. How faithfully the Muslims of later generations have followed these principles in running their governments is a matter of history. History will also judge Christian, Jewish and other governments of later generations on their adherence to their principles!

The Lord's Prayer compared to Surah Fateha
We see that both the Lord's prayer in the Bible and the Opening Chapter of the Qur'an (Sura al-Fateha), go to the root of all religions ever professed by man. They are truly universal prayers. No man need hesitate to join in the solemn recitation of either.

The Islamic prayer is simpler than the Christian prayer. We do not say that one is good and that the other is bad. No, both are very good indeed, however one seems simpler than the other. Let us compare them.

The Muslim Prayer
The Christian prayer
The Fateha [The Opening]

The Qur'an 1:1-7

The Lord's Prayer

Matthew 6:9-13
[The New Testament, King James version]

(a) Adoration
Praise be to God, Lord of the Worlds, the Compassionate, the Merciful. King of the Day of Reckoning.
(a) Adoration
Our Father who art in heaven,
Hallowed be thy name.
(b) Submission
Thee only do we worship and of Thee only do we ask aid.
(b) Submission
Thy Kingdom come.
Thy Will be done on earth as it is in heaven.
(c) Supplication
Guide us unto the right path - 
the path of those to whom Thou hast 
been gracious,
not the path of those who are the objects 
of Thy wrath, 
nor of those who have gone astray. 
(c) Supplication
Give us this day our daily bread.
And forgive us our debts as we forgive our debtors [Other translations say: "Forgive us our trespasses as we forgive those who trespass against us."]
And lead us not into temptation,
But deliver us from evil.
For Thine is the Kingdom,
The Power and the Glory.
For ever and ever. Amen

If we carefully compare the parts of each prayer which are written above as separate paragraphs (a) (b) and (c), we will observe that there are differences only in language, yet there are no differences whatsoever in meaning. There is in both prayers absolutely the same spirit of (a) Adoration (b) Submission and (c) Supplication.

It is also of interest to note that a Prophetic Tradition (Hadith) that is included in Abu Dawud's collection of Hadith is as follows: "Narrated Abu Darda': I heard the Apostle of Allah (peace be upon him) say: If any of you is suffering from anything or his brother is suffering, he should say: Our Lord is Allah Who is in the heaven, holy is Thy name, Thy command reigns supreme in the heaven and the earth, as Thy mercy in the heaven, make Thy mercy in the earth; forgive us our sins, and our errors; Thou art the Lord of good men; send down mercy from Thy mercy, and remedy, and remedy from Thy remedy on this pain so that it is healed up." [Sunan Abu Dawud, Book 28, Number 3883]

And nearest among them in love
To the Believers wilt thou
Find those who say, [789]
"We are Christians":
Because amongst these are
Men devoted to learning [790]
And men who have renounced
The world, and they
Are not arrogant.
Qur'an 5:82 Yusuf Ali Translation

Behold! God said: 
O Jesus, I will take thee [394]
And raise thee to Myself 
And clear thee (of the falsehoods) [395]
Of those who blaspheme; 
I will make those 
Who follow thee superior [396]
To those who reject faith, 
To the Day of Resurrection: 
Then shall ye all return unto Me, 
And I will judge 
Between you of the matters 
Wherein ye dispute. [397]
[Qur'an 3:55 Yusuf Ali translation]

What follows here are further points for a comparative study of Christianity and Islam (in simple columnar form) highlighting similarities and differences. We must also bear in mind the importance of the Qur'an's declaration which requires Muslims to regard Christians as their close friends:


Qur'an 35:13
He merges Night into Day, and he merges Day into Night, and he has subjected the sun and the moon (to his Law): each one runs its course for a term appointed. Such is Allah your Lord: to Him belongs all Dominion. And those whom ye invoke besides Him have not the least power. 
Genesis 1:14
Then God said, "Let there be lights in the expanse of the heavens to separate the day from the night,
and let them be for signs and for seasons and for days and years;
Qur'an 13:2
Allah is He Who raised the heavens without any pillars that ye can see is firmly established on the throne (of authority). He has subjected the sun and the moon (to his Law)! Each one runs (its course) for a term appointed. He doth regulate all affairs, explaining the signs in detail, that ye may believe with certainty in the meeting with your Lord. 
Genesis 1:1,2
In the beginning God created the heavens and the earth. The earth was formless and void, and darkness was over the surface of the deep, and the Spirit of God was moving over the surface of the waters.
Qur'an 13:3,4
And it is He who spread out the earth, and set thereon mountains standing firm and (flowing) rivers: and fruit of every kind He made in pairs, two and two: He draweth the night as a veil o'er the Day. Behold, verily in these things there are signs for those who consider!  And in the earth are tracts (diverse though) neighbouring, and gardens of vines and fields sown with corn, and palm trees - growing out of single roots or otherwise: watered with the same water, yet some of them We make more excellent than others to eat. Behold, verily in these things there are signs for those who understand! 
Genesis 1:9-12
Then God said, "Let the waters below the heavens be gathered into one place, and let  the dry land appear''; and it was so. God called the dry land earth, and the gathering of the waters He called seas; and God saw that it was good. Then God said, "Let the earth sprout vegetation: plants yielding seed, and fruit trees on the earth bearing fruit after their kind  with seed in them''; and it was so. The earth brought forth vegetation, plants yielding seed after  their kind, and trees bearing fruit with seed in them, after] their kind; and God saw that it was good.
Qur'an 41:37
Among His Signs are the Night and the Day, and the Sun and the Moon. Do not prostrate to the sun and the moon, but prostrate to Allah, Who created them, if it is Him ye wish to serve. 
Genesis 1:3-5
Then God said, "Let there be light''; and there was light. God saw that the light was good; and God  separated the light from the darkness. God called the light day, and the darkness He called night. And there was evening and there was morning, one day.
Qur'an 41:12
So He completed them as seven firmaments in two Days, and He assigned to each heaven its duty and command. And We adorned the lower heaven with lights, and (provided it) with guard. Such is the Decree of (Him) the Exalted in Might, Full of Knowledge. 
Genesis 1:14-18
Then God said, "Let there be lights in the expanse of the heavens to separate the day from the night, and let them be for signs and for seasons and for days and years; and let them be for lights in the expanse of the heavens to give light on the earth''; and it was so. God made the two great lights, the greater light to govern the day, and the lesser light to govern the night; He made the stars also. God placed them in the expanse of the heavens to give light on the earth,
and to govern the day and the night, and to separate the light from the darkness; and God saw that it was good.
Qur'an 50:38
We created the heavens and the earth and all between them in Six Days, nor did any sense of weariness touch Us. 
Genesis 2:1-3
Thus the heavens and the earth were completed, and all their hosts. By the seventh day God completed His work which He had done, and He rested on the seventh day from all His work which He had done. Then God blessed the seventh day and sanctified it, because in it He rested from all His work which God had created and made.
Qur'an 15:28,29
Behold! thy Lord said to the angels: "I am about to create man from sounding clay from mud molded 
into shape; when I have fashioned him (in due proportion) and breathed into him of My spirit fall ye down in obeisance unto him. 
Genesis 2:7
Then the Lord God formed man of dust from the ground, and breathed into his nostrils the breath of life; and man became a living being.

The Quranic teachings in this regard may be summed up as follows: (1) Christ was neither  crucified nor killed by the Jews, notwithstanding certain apparent circumstances which produced that illusion in the minds of some of the enemies; and (2) Jesus was taken up to God (i.e.. God raised him up (raf'a) to Himself.) [Qur'an 4:157, 158 & 3:55 & 4:157] Christians believe that Jesus was crucified on a cross.
See above. Christians believe Jesus was resurrected (raised from the dead) three days after being crucified on a cross (Good Friday to Easter Sunday are the days when Christians remember and celebrate this.) Jesus' crucifixion they believe, redeems Christians of their sins.
Eschatology - Judgement will occur on Judgement Day (the end of the world when God will judge all human beings beginning from Adam and Eve). Persons who have been previously deceased, and are in their graves, are given an indication (via 'windows' in the grave) of what his or her future Judgement may be. The punishment of the grave will begin immediately. Rewards begin immediately too. (This intermediate stage of the grave may be regarded as similar to the Catholic Purgatory, and is called barzakh in Islam). The final abode of either Paradise or Hell will be pronounced on the Day of Judgement. Eschatology -  most Christians believe that judgement takes place, immediately upon death (i.e. they will either go to Heaven or Hell, or as in the case of Catholics, they  could also go to Purgatory immediately upon death). Christians also believe that the final Judgement Day is only for all those people who have not died yet and will be for those remaining on earth.
Hell is a place of purification, and is permanent. Paradise as a reward, and Hell as a punishment are but graphic terms to make us understand a state of things which is beyond all our notions of life in that world. Paradise will be eternal. Once meriting it, there can be no question of being ejected from it. As to whether Hell is also eternal for the unbelievers, there are two schools of thought: (1) A great majority of Muslims affirm that God may  pardon every sin and every crime except disbelief in God. [Qur'an 4:48,116]
(2) Others believe that even the punishment of disbelief may one day terminate by the grace of God. [Qur'an 11:107, etc.] 
The Qur'an 4:124 declares: "If any do deeds of righteousness - be they male or female - and have faith, they will enter Paradise and not the least injustice will be done to them." In other words no religion has a monopoly on salvation!
Hell is eternal, but Purgatory is not (note: Catholics believe in Purgatory whereas Protestants do not). While Catholics believe that Purgatory is precisely the same as Hell, it is not eternal. They believe it is a place or state of punishment wherein the souls of those who die in God's grace may do penance for past sins and hence become cleansed and fit for heaven. Only Christians can go to heaven.
All mankind is born pure and he/she is responsible for his or her own sins and not someone else's. Christians believe in Original Sin, (all of mankind is held responsible for the sins of Adam and Eve) which only the sacrament of baptism in the name of Christ can expiate.
Muslims do not believe in vicarious atonement. They believe that each person is responsible for his or her own actions and that no-one else can atone for them. However, you can pray to God for His Mercy and Forgiveness on behalf of another person. The Prophet Muhammad, p.b.u.h. -- and some others (like innocent babies who have passed away) are given the special privilege to intercede on behalf of their parents on the Day of Judgement. This is in accord with the Throne Verse in the Qur'an. So  with God's graceful permission, they may have a specially bestowed privilege of pleading on behalf of others and begging for God's forgiveness for them on the Day of Judgement. This is known as intercession (shafa't). Christians believe in vicarious atonement -- that another person can extinguish the guilt incurred by another person's sins. Jesus is believed to have died so as to atone vicariously for man's sins. He was considered to be the Lamb of God, which means that Jesus was considered to be the perfect sacrifice by which the hold of Original Sin was broken. Christians believe in intercession and intercessors such as priests and monks.
The holy Qur'an was revealed ('revelation' [wahi] is the highest form of inspiration with no possibility of error in the message or the conveyance of the message) to the Prophet Muhammad, p.b.u.h. through the angel Gabriel who was carrying out God's precise instructions. This occurred over a period of 23 years. The holy Qur'an is God's Word -- not the word of the Prophet Muhammad, p.b.u.h. Christians believe that divine inspiration (the Latin word is 'afflatus' which  means 'divine wind') inspired the writers of the scripture. Hence they believe that the Gospel of St. Mark (obviously written by St. Mark) or the letters of Paul the Apostle are the "Word of God."
The Qur'an exists today exactly the same as it was revealed to Muhammad, p.b.u.h. There have been absolutely no changes whatsoever made to the wording. Special checks and balances and special means for the preservation of accuracy (.e.g. memorizing of the text by many people, etc. etc.) were put into place so that no error or change could possibly creep into the text. A council was called, in the early days of Christianity, where the church fathers and elders debated. This was presided over by the Roman (and Christian) Emperor Constantine (circa 324 A.D.). This council codified (systematized) standard Christian belief and gave the New Testament its present form, depriving some books of the status of Scripture (many of which still exist today and are known as the Apocrypha).
All the Prophets, from Adam a.s. to Muhammad p.b.u.h. are pure and sinless/infallible. In the Old Testament (Jewish scriptures which most Christians regard as authoritative), Prophets are not portrayed as being infallible to say the least.
There are many differences between the Quranic and the Biblical versions in the details of certain Biblical stories. There are many differences between the Quranic and the Biblical versions in the details of certain Biblical stories.
The first source of Muslim Law, is the Qur'an. The second source of law is the Hadith (Traditions of the Prophet Muhammad, p.b.u.h.). The Hadith literature expounds and explains and interprets the Quranic injunctions and teachings. The Hadith do not contradict the Qur'an in any way. The source of Christian (or Canon) Law is the scripture, which has been interpreted by the Pope for Catholics; by the Patriarch for members of the Orthodox faith; and by the consensus of the community for other groups. The writings of the church fathers would also be relevant.
For Muslims, Prophets are spiritually advanced and are very pure and sinless. They have been sent by God to guide and teach mankind. There have been 127,000 of them from Adam, a.s. to Muhammad p.b.u.h. who was the last Prophet sent, meaning that no more Prophets will come after him. Hence Muhammad p.b.u.h. was called the "Seal of the Prophets." The Prophets were sent as Messengers of God to people in different countries at different times. Prophets do not have the same stature in Christianity that they have in Islam.

(ii) Moral Code

Islam does not treat law and morality as different things. What is legal/lawful is also moral and conversely what is unlawful/illegal is also immoral. Consequently, Islamic law automatically covers and governs morality -- moral values are not changeable nor are they dependant on the whims of individuals or society. The Islamic legal system combines the two opposites: a) rigid inflexibility and permanency through the Shar'iah (i.e. the divine injunctions of the Qur'an and the Sunnah) and b) the flexibility and fluidity to accommodate man-made legislation with the changing needs of society. There are two forms of legal systems in Islam: i) Fiqh (which cannot be inconsistent with the Shariah) and ii) the derivative form of legislation which is based on the Shariah. Transgressing these two regulations or bounds will make Fiqh (i.e. man-made legislation) ultra vires ab-initio (i.e. absolutely void from the beginning.) Secular law, and morality are often different things. For example, abortion is considered legal by the government in Canada. Many Protestants have no problem with this law, yet Catholics forbid it for their followers. What is considered moral has tended to change with each generation. The guideposts and/or criteria of what is considered moral or what is considered immoral are interpreted differently depending on the era or the group (Catholic, Protestant, etc.). Church doctrine, while it can change and be altered, doesn't change so often as  the church members interpretations of it do. For example, Jesus' commandment "Love thy neighbour as thyself" has differing interpretations on how to carry it out depending on the time and era and generation; also compliance to this commandment has changed substantially from place to place, group to group and time to time.
Muslims believe that while the Scripture and Gospels were originally pure and error free, contradiction and error has crept into them over time and so now the current books are considered to be highly suspect. For example we don't know what are really Jesus', a.s. words from what are the scribes words because there were no checks and balances that were put into place to ensure that such errors did not occur. Hence we see several contradictions in both the Old Testament and the New Testament.  Even though the Old Testament is regarded as Scripture, Christians do not regard themselves as being bound by Jewish law (this thanks to a dream of St. Peter).
Muslims, like Jews do not consume the flesh of swine. Christians consume the flesh of swine.
Alcohol and/or intoxication is completely forbidden. Alcohol intoxication is forbidden for Christians, but alcohol consumption is not.
Free-mixing of sexes is discouraged. Free-mixing of the sexes was historically discouraged, but today this injunction doesn't play the role it used to.

(iii) Practices

Muslims do not believe in the separation of 'church from state' (i.e. secularism). However, it is permissible to separate the functions of government (politics) from religion and be undertaken by different individuals -- politics would still be subject to religion. Almost all Christian countries have secular governments.
The Muslim daily rituals and practices are clear and detailed (e.g. proper way to use the washroom, specifics of purification for prayer, inheritance, details of Zakat, prescribed punishments, etc.). Lack the details that Islam holds.
Prayer is very specific and exactly the same no matter which country the Muslim happens to live in. There are five prescribed prayers per day at set times according to the rotation of the earth around the sun. All of these prayers are obligatory on every Muslim. The prescribed prayers are recited in Arabic and are recited exactly the same in all countries of the world. The culture of a person does not influence the performance of prayer (salat). It is the exact prayer that Muhammad, p.b.u.h. taught us to do. With a few memorized exceptions, like the 'Our Father' and the 'Apostle's Creed,' prayer is an improvised conversation with God; there is no prescribed time for nor daily number of Christian prayers.
Actions may be haram (forbidden), halal (allowed), fard (obligatory), sunnah (following the ways of the Prophet Muhammad, p.b.u.h.) and so on. Don't have any specific categories of actions as seen in Muslim law.
Funeral prayers, the birth of a baby (adhan), donations to charity (i.e. Zakat) etc. are ritualized and clearly set out no matter which culture a Muslim belongs to. Certain rites called sacraments are performed: i.e.  Baptism, Confession, the Eucharist, etc.
Hymns and devotional services of worship and supplications are an integral part of all Muslim forms of worship. Zikr ceremonies (chanting a name of God), and sama (religious music) are practised more often among the more devout groups of Muslims such as the Sufis.  Hymns and devotional music play a big role in Christianity.
In Islam, there is no institutionalized "church" nor its hierarchy. There are no monks in Islam either. Religious leaders are not obliged to remain celibate. Certain sects (i.e. large sects like the Catholic and Eastern Orthodox churches) condone monkhood. Catholic monks and priests are obliged to remain celibate. Protestant ministers are not obliged to remain celibate.
Muslims are forbidden to put pressure, either directly or indirectly, on another person to convert to Islam. Efforts in this regard have to be through persuasion (i.e. without involving any kind of pressure). The Qur'an clearly lays down the law that the duty and function of all the Prophets and all Muslims is only to convey the message of God. Period.  Christians have an obligation to proselytize. Missionary work is considered very important.
Homosexuality is considered to be a perversion and is forbidden. Since the prohibition on homosexuality is found in the Old Testament only, some Christian sects say it does not apply (i.e. the United Church ordains homosexual ministers).
Interest (riba) is forbidden to Muslims who live in Islamic countries.  Interest used to be forbidden in Christianity, but it seems that this is no longer the case.
Polygamy is allowed to Muslims. There are strict limitations and prohibitions concerning it so it does not become a method to dominate women. Polygamy used to be allowed by the Church, but now it is forbidden to all sects but the Mormons.
All games of chance and gambling are forbidden in Islam. Some sects are very strict about gambling, but others are not strict at all.
Only females are allowed to wear gold Males and females are allowed to wear gold.


Islamic Secularism
Christian Secularism

O Beloved! Did you not see a group (or Chiefs) of the Children of Israel after Moosa (Moses)? When they spoke to a prophet of theirs: ‘raise for us a king that we may fight in the way of Allah….’
“And their prophet said to them: ‘Verily Allah has sent Talut [the Biblical Saul]  as your king … and has increased him in knowledge and physique.”(Quran 2:246)

The Quranic word ‘Talut’ is itself expressive of  tallness; and that he was tall and stood high is mentioned in the Bible too:


He [Saul] was higher than any of the people from his shoulders on upwards (The First Book of Samuel 10:23).

(The First Book of Samuel, 8: 4-5; 19-20)
“… Then all the elders ofIsrael gathered themselves together, and came to Samuel  unto Ramah, and said unto him… Now make us a king to judge us like all the nations… We will have a king over us, that we also may be like all the nations; and that our king may judge us, and go out before us, and fight our battles.”

“In war he [Saul] was able to march 120 miles without rest” (The Book of Jeremiah). It was a fixed belief with the Hebrews that their leader, besides possessing other qualities, must be tall of stature. ‘The Holy One, blessed be He, does not cause His Shechinah to alight except on one who is wise, strong, rich, and tall of stature.” (Cohen’s ‘Everyman’s Talmud, [Dent, London] p. 126)


Islamic Secularism
Christian Secularism
Islam attaches no importance to the external form of government. It is satisfied if the well-being of a person  in both the worlds is aimed for, and the Divine law applied. 
     Thus constitutional questions take a secondary place. 
     Thus, a republic, a monarchy, a joint-rule, among other forms, are all valid in the Islamic community. 
      If this aim is realized by a single chief, one accepts it. If at a given time, in a given surrounding, all the requisite qualities of a "commander of the Faithful" or caliph are not found united in the same person, one admits that the division of power is for the purpose of the better functioning of the government. 
     A famous case cited by the Qur'an (2:246-47) is of a former prophet who was solicited by his people to select for them a king beside himself [don't forget he was a prophet too], so that they might wage war under his leadership, against the enemy which had expelled them from their homes and familes. 
     The designation of a king in the presence of and in addition to a prophet, and even by the intermediary of the latter, shows the lengths to which one can go in this direction. A division is is thus made between the spiritual and temporal functions, yet no arbitrary power is tolerated for either of them. 
     The politics and the king remain as much subject to the Divine law as the cult and the prophet. The source of authority and codes of law remain the same, only the application of law and the execution of necessary dispositions relate to different persons. It is more a question of specialization than a divorce between the two aspects of life. 

Islam has kept the original meaning of the Quranic text whereby both the spiritual and temporal functions of the government are governed by the Divine Scriptures. One can see the close similarity of the Quranic and the Biblical texts. here.
Biblical Secularism has been reinterpreted in modern times. The initial Biblical text does not provide for the separation of the Church and State in a way that it was correctly interpreted to mean  [i.e. that although the Church is governed by the Divine Scripture, the State is not supposed to be governed by the Divine Scriptures but rather by the man-made laws of Caeser.]

Matthew 22

21   They say unto him, Caesar's. Then saith he unto them, Render therefore unto Caesar the things which are Caesar's; and unto God the things that are God's.

The maxim “Render unto Caesar . . . the things that are Caesar's, and to God the things that are God’s” has become the cardinal doctrine under which modern Christian/Western governments operate.

The current definition cited in the opposite column is much used in the west and it is spreading to the east. The current definition:

Secularism: indifference to or rejection or exclusion of religion and religious considerations


Notes to the Yusuf Ali translation of the Qur'an

[789] The meaning is not that they merely call themselves Christians, but that they are such sincere Christians that they appreciate Muslim virtues, as did the Abyssinians to whom Muslim refugees went during the persecution in Mecca. They would say: "It is true we are Christians, but we understand your point of view, and we know you are good men." They are Muslims at heart, whatever their label may be.

[790] Qissis: I have translated as "devoted to learning," following the Commentators. It seems to be a foreign word, possibly Abyssinians rather than Syriac as the reference seems to be to the Abyssinian Christians. Their real devotions to learning and the renunciation of the world by the Monastic Orders are contrasted with the hypocrisy and arrogance of the Pharisees and Scribes.

[394] Read this along with Quranic verse 4:157, where just like that it is said that the Jews neither crucified nor killed Jesus, but that another was killed in his likeness. The guilt of the Jews remained, but Jesus was eventually taken up to God.

[395] Jesus was charged by the Jews with blasphemy as claiming to be God or the Son of God. The Christians, (except a few early sects which were annihilated by persecution, and the Unitarians [in Yusuf Ali's time] who are almost Muslims) adopted the substance of the claim and made it the cornerstone of their faith. God clears Jesus of such a charge of claim.

[396] The Muslims are the true Christians, for they follow (or should follow) the true teachings of Christ, which did not include the blasphemy that he was God or the Son of God in the literal sense. But there is a large body of men, who by birth inherit such teaching nominally, but their hearts do not consent to it. Their real Muslim virtues (which from their point of view they call Christian virtues) entitle them to be called Christians, and to receive the leading position which they at present occupy in the world of men.

[397] All the controversies about dogma and faith will disappear when we appear before God. He will judge not by what we profess, but by what we are.

"injil has been lost"  . . . For example, many Christians believe the the New Testament Gospels were written from one and the same source which has come to be known as "Q" which has been lost to antiquity. Matthew, Mark, Luke and John were believed to have seen this source material. For more detailed information click here.
