Osama bin Laden follows a conservative form of Islam known as Wahhabi Islam. As part of his religious convictions, Osama believes that it is his sacred duty to hate non-Muslims. In his own words, “Every Muslim, from the moment they realize the distinction in their hearts, hates American, hates Jews, and hates Christians. This is a part of our belief and our religion.” Osama has also stated that “Killing Americans is the duty of any orthodox Muslim.”
This belief is derived from several passages in the Quran, include Sura 5; Verse 80, “Thou seest many of them making friends with those who disbelieve. Surely ill for them is that which they themselves send on before them: that Allah will be wroth with them and in the doom they will abide.”
Osama believes that it is the sacred duty of every Muslim to wage holy war (jihad) on all non-Muslims until they submit to Muslim rule. This belief also arises from several Quranic passages:
Sura 2; Verse 216: Warfare is ordained for you, though it is hateful unto you; but it may happen that ye hate a thing which is good for you, and it may happen that ye love a thing which is bad for you. Allah knoweth, ye know not.
Sura 8; Verse 65: O Prophet! Exhort the believers to fight. If there be of you twenty steadfast they shall overcome two hundred, and if there be of you a hundred (steadfast) they shall overcome a thousand of those who disbelieve, because they (the disbelievers) are a folk without intelligence.
Sura 8; Verse 66: Now hath Allah lightened your burden, for He knoweth that there is weakness in you. So if there be of you a steadfast hundred they shall overcome two hundred, and if there be of you a thousand (steadfast) they shall overcome two thousand by permission of Allah. Allah is with the steadfast.
Sura 8; Verse 67: It is not for any prophet to have captives until he hath made slaughter in the land. Ye desire the lure of this world and Allah desireth (for you) the Hereafter, and Allah is Mighty, Wise.
Sura 9; Verse 5: Then, when the sacred months have passed, slay the idolaters wherever ye find them, and take them (captive), and besiege them, and prepare for them each ambush. But if they repent and establish worship and pay the poor-due, then leave their way free. Lo! Allah is Forgiving, Merciful.
Sura 9; Verse 29: Fight against such of those who have been given the Scripture as believe not in Allah nor the Last Day, and forbid not that which Allah hath forbidden by His messenger, and follow not the Religion of Truth, until they pay the tribute readily, being brought low.
Sura 9; Verse 123: O ye who believe! Fight those of the disbelievers who are near to you, and let them find harshness in you, and know that Allah is with those who keep their duty (unto Him).
Sura 47; Verse 4: Now when ye meet in battle those who disbelieve, then it is smiting of the necks until, when ye have routed them, then making fast of bonds; and afterward either grace or ransom till the war lay down its burdens. That (is the ordinance). And if Allah willed He could have punished them (without you) but (thus it is ordained) that He may try some of you by means of others. And those who are slain in the way of Allah, He rendereth not their actions vain.
Osama is working to create a single global Islamic caliphate which will be ruled by sharia law. This will be a post-nationalist state where nations disappear or become irrelevant, because all governing will be done by Islamic clergy. To accomplish this goal, he must defeat all existing governments. This is a major task, and one which Osama most likely does not believe will be accomplished in his own lifetime. This is why Osama created Al Qaeda — to carry on his work after his death.
As a result of his Islamic beliefs, Osama bin Laden has specifically criticized Americans for fornication, homosexuality, intoxicants, gambling, and usury. In addition, Osama is opposed to music and chilled water, because he believes they are un-Islamic.
