Quran (2:191-193) - "And kill them wherever you find them, and turn them out from where they have turned you out. And Al-Fitnah [disbelief or unrest] is worse than killing...
but if they desist, then lo! Allah is forgiving and merciful. And fight them until there is no more Fitnah [disbelief and worshipping of others along with Allah] and worship is for Allah alone. But if they cease, let there be no transgression except against Az-Zalimun (the polytheists, and wrong-doers, etc.)" (Translation is from the Noble Quran) The historical context of this passage is not defensive warfare, since Muhammad and his Muslims had just relocated to Medina and were not under attack by their Meccan adversaries. In fact, the verses urge offensive warfare, in that Muslims are to drive Meccans out of their own city (which they later did). The use of the word "persecution" by some Muslim translators is thus disingenuous (the actual Muslim words for persecution - "idtihad" - and oppression - a variation of "z-l-m" - do not appear in the verse). The actual Arabic comes from "fitna" which can mean disbelief, or the disorder that results from unbelief or temptation. Taken as a whole, the context makes clear that violence is being authorized until"religion is for Allah" - ie. unbelievers desist in their unbelief.
Quran (2:244) - "Then fight in the cause of Allah, and know that Allah Heareth and knoweth all things."
Quran (2:216) - "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." Not only does this verse establish that violence can be virtuous, but it also contradicts the myth that fighting is intended only in self-defense, since the audience was obviously not under attack at the time. From the Hadith, we know that this verse was narrated at a time that Muhammad was actually trying to motivate his people into raiding merchant caravans for loot.
Quran (3:56) - "As to those who reject faith, I will punish them with terrible agony in this world and in the Hereafter, nor will they have anyone to help."
Quran (3:151) - "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". This speaks directly of polytheists, yet it also includes Christians, since they believe in the Trinity (ie. what Muhammad incorrectly believed to be 'joining companions to Allah').
Quran (4:74) - "Let those fight in the way of Allah who sell the life of this world for the other. Whoso fighteth in the way of Allah, be he slain or be he victorious, on him We shall bestow a vast reward." The martyrs of Islam are unlike the early Christians, who were led meekly to the slaughter. These Muslims are killed in battle as they attempt to inflict death and destruction for the cause of Allah. This is the theological basis for today's suicide bombers.
Quran (4:76) - "Those who believe fight in the cause of Allah…"
Quran (5:33) - "The punishment of those who wage war against Allah and His messenger and strive to make mischief in the land is only this, that they should be murdered or crucified or their hands and their feet should be cut off on opposite sides or they should be imprisoned; this shall be as a disgrace for them in this world, and in the hereafter they shall have a grievous chastisement"
Quran (8:12) - "I will cast terror into the hearts of those who disbelieve. Therefore strike off their heads and strike off every fingertip of them" No reasonable person would interpret this to mean a spiritual struggle.
Quran (9:73) - "O Prophet! strive hard against the unbelievers and the hypocrites and be unyielding to them; and their abode is hell, and evil is the destination." Dehumanizing those who reject Islam, by reminding Muslims that unbelievers are merely firewood for Hell, makes it easier to justify slaughter. It also explains why today's devout Muslims have little regard for those outside the faith.
Quran (9:88) - "But the Messenger, and those who believe with him, strive and fight with their wealth and their persons: for them are (all) good things: and it is they who will prosper."
Quran (9:111) - "Allah hath purchased of the believers their persons and their goods; for theirs (in return) is the garden (of Paradise): they fight in His cause, and slay and are slain: a promise binding on Him in truth, through the Law, the Gospel, and the Quran: and who is more faithful to his covenant than Allah? then rejoice in the bargain which ye have concluded: that is the achievement supreme." How does the Quran define a true believer?
Quran (9:123) - "O you who believe! fight those of the unbelievers who are near to you and let them find in you hardness."
Bukhari (52:220) - Allah's Apostle said... 'I have been made victorious with terror'
