A young Arab, part of an oversized family, competing for scarce jobs, unable to marry because he is poor, perhaps a migrant to a rapidly expanding city, feels like a man lost in a desert without signposts. One morning he picks up a copy of Sayyid Qutb from a newsstand, and is 'born-again' on the spot. This is what he needed: instant certainty, a framework in which to interpret the landscape before him, to resolve the problems and tensions of his life, and, even more deliciously, a way of feeling superior and in control. He joins a group, and, anxious to retain his newfound certainty, accepts the usual proposition that all the other groups are mistaken.
This, of course, is not how Muslim religious conversion is supposed to work. It is meant to be a process of intellectual maturation, triggered by the presence of a very holy person or place. Tawba, in its traditional form, yields an outlook of joy, contentment, and a deep affection for others. The modern type of tawba, however, born of insecurity, often makes Muslims narrow, intolerant, and exclusivist. Even more noticeably, it produces people whose faith is, despite its apparent intensity, liable to vanish as suddenly as it came. Deprived of real nourishment, the activist's soul can only grow hungry and emaciated, until at last it dies.
On a whim, I did a search through the text for "Shi'a" and "Shia" but apparently the essay does not reference Shi'a theological perspectives.
