That statement is something I would challenge. In terms of scripture, looking at the fundamentals such as the Qur’an and Hadith, one can see that verses and accounts describing, glorifying and commanding the violent subjugation of non-believers are overflowing in the texts. The following is a response I wrote to a person who was enquiring about Islam with similar misconceptions (that the fundamental tenants of Islam are based on peace):
I would suggest further research into the mechanics of understanding the Qur’an. The view you have purported is very naive in the context of abrogation (al-naskh wa al-mansukh) and the actual words and deeds of Mohammed.
The Qur’an cannot merely be read at face value without its companions the Hadith (oral traditions relating to the words and deeds of Muhammad) and the Sira (traditional Muslim biographies of Muhammad). The Qur’an was not compiled chronologically and it has been left to scholars to interpret a timeline of the verses based on information from, among others but mostly, the Hadith and the Sira.
Once you have this in mind you would understand that Muhammad issued platitudes towards other monotheistic religions (“the people of the book”) in a time when Islam was still a new movement in Mecca and still relatively weak as a whole.
However, once Muhammad and his follows attained military fortitude following their migration to Medina all of Muhammad’s previous platitudes towards “the people of the book” (and unbelievers as a whole) are abrogated by what he proclaimed in this later Medinan period.
The verse of abrogation (“al-naskh wa al-mansukh”):
“Whatever a Verse (revelation) do We {Allah} abrogate or cause to be forgotten, We bring a better one or similar to it. Know you not that Allah is able to do all things?” -(2:106)
So, an example of abrogation is the classic “no compulsion in religion” verse Islamic apologists use all the time:
“There is no compulsion in religion. Verily, the Right Path has become distinct from the wrong path. Whoever disbelieves in Taghut {idolatry} and believes in Allah, then he has grasped the most trustworthy handhold that will never break.” -(2:256)
All very nice, unfortunately this verse was “revealed” when the Muslims were still weak, having fled Mecca for Medina. It has since been abrogated (made null and void) since what Muhammad “revealed” after this period completely contradicts it.
For example, the classic “Verse of the Sword”:
“Then when the Sacred Months (the 1st, 7th, 11th, and 12th months of the Islamic calendar) have passed, then kill the Mushrikun {unbelievers} wherever you find them, and capture them and besiege them, and prepare for them each and every ambush. But if they repent and perform As-Salat (Iqamat-as-Salat {the Islamic ritual prayers}), and give Zakat {alms}, then leave their way free.” -(9:5)
So, from the Medinan period it was commanded that Muslims were to go out through out the world and conquer all non-Muslim lands (jihad), incorporate them into Dar al-Islam (the land of Islam) and either convert the infidels or subjugate them as dhimmi people under Islamic control (Sharia) where they would live at the mercy of their Islamic overlords all the while paying the jizya (tribute tax) for the luxury of remaining non-Muslim and alive.
Here is the evidence, judge for yourself:
“And fight them until there is no more Fitnah (disbelief and polytheism: i.e. worshipping others besides Allah) and the religion (worship) will all be for Allah Alone [in the whole of the world]. But if they cease (worshipping others besides Allah), then certainly, Allah is All-Seer of what they do.” -(8:39)
“Fight against those who believe not in Allah, nor in the Last Day, nor forbid that which has been forbidden by Allah and His Messenger and those who acknowledge not the religion of truth (i.e. Islam) among the people of the Scripture (Jews and Christians), until they pay the Jizya with willing submission, and feel themselves subdued.” -(9:29)
“It is He {Allah} Who has sent His Messenger (Muhammad) with guidance and the religion of truth (Islam), to make it superior over all religions even though the Mushrikun (polytheists, pagans, idolaters, disbelievers in the Oneness of Allah) hate (it).” -(9:33)
What’s that about Islam and terrorism having nothing to do with each other? Well…
“Soon shall We cast terror into the hearts of the Unbelievers, for that they joined companions with Allah, for which He had sent no authority.” -(3:151)
“I will cast terror into the hearts of those who disbelieve. Therefore strike off their heads and strike off every fingertip of them” -(8:12)
And, in case you’re wondering, yes, jihad and the struggle for Islamic dominance over the infidels is mandatory for Muslims in some form or another. (Allah even offers extra status and extra rewards to those who do):
“Fighting is prescribed for you, and ye dislike it. But it is possible that ye dislike a thing which is good for you, and that ye love a thing which is bad for you. But Allah knoweth, and ye know not.” -(2:216)
“Those who believe fight in the cause of Allah…” -(4:76)
“Not equal are those believers who sit (at home) and receive no hurt, and those who strive and fight in the cause of Allah with their goods and their persons. Allah hath granted a grade higher to those who strive and fight with their goods and persons than to those who sit (at home). Unto all (in Faith) Hath Allah promised good: But those who strive and fight Hath He distinguished above those who sit (at home) by a special reward,-” -(4:95)
Finally, the Qur’an is very succinct in its view of non-Muslims. They are the scorn of Allah, damned to burn in hell and it is the duty of Muslims to either convert them or to subjugate them as dhimmis. If they do not do this they are, simply, to be killed.
“Those who reject (Truth), among the People of the Book and among the Polytheists, will be in Hell-Fire, to dwell therein (for aye). They are the worst of creatures.” - (98:6)
“And the Jews say: Uzair is the son of Allah; and the Christians say: The Messiah is the son of Allah; these are the words of their mouths; they imitate the saying of those who disbelieved before; may Allah destroy them; how they are turned away!” - (9:30)
“Against them make ready your strength to the utmost of your power, including steeds of war, to strike terror into (the hearts of) the enemies of Allah and your enemies and others besides, whom ye may not know” -(8:60)
“Strive hard (Jihad) against the Unbelievers and the Hypocrites, and be firm against them. Their abode is Hell,- an evil refuge indeed.” -(66:9)
I would quote more but there really is no point. The Qu’ran is overflowing with hatred for all things non-Islamic. Hell, some of Muhammad’s own final words were: “May Allah curse the Jews and Christians.” -(Bukhari 8:427)
Finally, I would just like to point out that all of my direct quotation has come from the Qur’an (barring the final words of Muhammad which came from the Hadith).
