"Does the Quran preach killing of infidels?" The Quran only asks followers of the faith to defend themselves from those who violently attack them or their faith and persecutes them to stop them from following their chosen faith - in the manner of "God helps those who help themselves" and that survival (therefore self defence) is the highest virtue. This wikipedia entry explains how the Quran is sometimes misquoted selectively out of context to mean that it preaches violence against non believers: Quran and violence
Bullshit.
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.)"
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 (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. The targets of violence are "those who disbelieve" - further defined in the next verse (13) as "defy and disobey Allah." Nothing is said about self-defense. In fact, the verses in sura 8 were narrated shortly after a battle provoked by Muhammad, who had been trying to attack a lightly-armed caravan to steal goods belonging to other people.
Quran (8:59-60) - "And let not those who disbelieve suppose that they can outstrip (Allah's Purpose). Lo! they cannot escape. Make ready for them all thou canst of (armed) force and of horses tethered, that thereby ye may dismay the enemy of Allah and your enemy." As Ibn Kathir puts it in his tafsir on this passage, "Allah commands Muslims to prepare for war against disbelievers, as much as possible, according to affordability and availability."
Quran (9:5) - "So when the sacred months have passed away, then slay the idolaters wherever you find them, and take them captive and besiege them and lie in wait for them in every ambush, then if they repent and keep up prayer and pay the poor-rate, leave their way free to them." According to this verse, the best way of staying safe from Muslim violence at the time of Muhammad was to convert to Islam: prayer (salat) and the poor tax (zakat) are among the religion's Five Pillars. The popular claim that the Quran only inspires violence within the context of self-defense is seriously challenged by this passage as well, since the Muslims to whom it was written were obviously not under attack. Had they been, then there would have been no waiting period (earlier verses make it a duty for Muslims to fight in self-defense, even during the sacred months). The historical context is Mecca after the idolaters were subjugated by Muhammad and posed no threat. Once the Muslims had power, they violently evicted those unbelievers who would not convert.
Deuteronomy 17:
If there be found among you, within any of thy gates which the LORD thy God giveth thee, man or woman, that hath wrought wickedness in the sight of the LORD thy God, in transgressing his covenant; 17:3 And hath gone and served other gods, and worshipped them, either the sun, or moon, or any of the host of heaven, which I have not commanded; 17:4 And it be told thee, and thou hast heard of it, and enquired diligently, and, behold, it be true, and the thing certain, that such abomination is wrought in Israel; 17:5 Then shalt thou bring forth that man or that woman, which have committed that wicked thing, unto thy gates, even that man or that woman, and shalt stone them with stones, till they die.
Deuteronomy 13:
6 If your very own brother, or your son or daughter, or the wife you love, or your closest friend secretly entices you, saying, “Let us go and worship other gods” (gods that neither you nor your ancestors have known, 7 gods of the peoples around you, whether near or far, from one end of the land to the other), 8 do not yield to them or listen to them. Show them no pity. Do not spare them or shield them. 9 You must certainly put them to death. Your hand must be the first in putting them to death, and then the hands of all the people. 10 Stone them to death, because they tried to turn you away from the Lord your God, who brought you out of Egypt, out of the land of slavery. 11 Then all Israel will hear and be afraid, and no one among you will do such an evil thing again.
12 If you hear it said about one of the towns the Lord your God is giving you to live in 13 that troublemakers have arisen among you and have led the people of their town astray, saying, “Let us go and worship other gods” (gods you have not known), 14 then you must inquire, probe and investigate it thoroughly. And if it is true and it has been proved that this detestable thing has been done among you, 15 you must certainly put to the sword all who live in that town. You must destroy it completely, both its people and its livestock. 16 You are to gather all the plunder of the town into the middle of the public square and completely burn the town and all its plunder as a whole burnt offering to the Lord your God. That town is to remain a ruin forever, never to be rebuilt.
