“Perhaps the most dangerous element that was picked out of the Muslim tradition and changed and transformed in the hands of these young men who perpetrated Sept. 11 is this idea of committing suicide. They call it martyrdom, of course. Suicide is firmly rejected in Islam as an act of worship. In the tradition, generally, to die in battle for a larger purpose -- that is, for the sake of the community at large -- is a noble thing to do. Self-sacrifice yourself as you defend the community -- that is a traditional thing, and that has a traditional meaning of "jihad." But what is non-traditional, what is new is this idea that jihad is almost like an act of private worship. You become closer to God by blowing yourself up in such a way. You, privately, irrespective of what effect it has on everyone else…. For these young men, that is the new idea of jihad. This idea of jihad allows you to lose all the old distinctions between combatants and non-combatants, between just and unjust wars, between the rules of engagement of different types. All of that is gone, because now the act of martyrdom is an act of worship… in and of itself. It's like going on the pilgrimage. It's like paying your alms, which every Muslim has to do. It's like praying in the direction of Mecca, and so on and so forth. It is an individual act of worship. That's terrifying, and that's new. That's an entirely new idea, which these young men have taken out, developed.”
