the role of religion in the social fabric of Islamic societies is quite different from that of Christianity in ours. Islam does not only relate humans to the hereafter, like all religions do, and determine what is good and evil, but it also defines what is legal or illegal in a juridical sense, legitimate and illegitimate in a political sense, true and untrue in an empirical sense. Islam is, so to speak, the DNA of its societies: not only a religion but a social system.
