elaborated in a number of sayings attributed to Muhammad. But there are also sayings that put strict limits on the duty of obedience. Two dicta attributed to the Prophet and universally accepted as authentic are indicative. One says, "there is no obedience in sin"; in other words, if the ruler orders something contrary to the divine law, not only is there no duty of obedience, but there is a duty of disobedience. This is more than the right of revolution that appears in Western political thought. It is a duty of revolution, or at least of disobedience and opposition to authority. The other pronouncement, "do not obey a creature against his creator," again clearly limits the authority of the ruler, whatever form of ruler that may be.
