“I find it very significant that no religious traditions, Islam included, is ever in a position, I think almost by definition, to put cruelty first in the order of its priorities of the terrible things that human beings can do. That is perfectly illustrated in the story of Abraham's sacrifice with his son. Because, of course, what the story's all about is faith, the importance, and the primacy of faith. … What is the essence of faith in the story is Abraham's willingness (a) not to question God about his command to sacrifice his son, and (b) to proceed slowly, deliberately, over a period of time -- three days, I think it was -- [and] march up the mountain, prepare the sacrifice, unquestioning, resolute. [It was] the perfect, as Kierkegaard put it, "night of faith" model, exemplar of faith. And [Abraham] is, in the Muslim tradition exactly that -- an exemplar of faith. That is the importance of Abraham to Muslims. … Had he faltered, his faith would have been less, a degree or so less. He didn't falter. God immediately stops it at the absolute last moment and, of course, the act is ended. But what the story is all about is how faith in God comes first, before anything else, and then follow various virtues, of which harm to other human beings surely has to be below faith. It seemed to me that that is something that the hijackers certainly took to heart.”
