Human destiny, by Islamic lights, is a matter of man having been placed on this earth by God, so that he may be put to the test – the test being of his capacity to make correct moral choices. It is for this purpose that man has been given complete freedom, for without such freedom, the divine test would have no meaning, no validity. It is required of man that he should lead his life on earth following a regimen of strict self-discipline. Wherein should he find the guiding principles for such a course? The answer, according to Islam, is in prophethood.
