Surah 37. As-Saffat, Ayah 37

See surah {2}, note [5]. It is to be borne in mind that this refers to the fundamental teachings, which have always been the same in every true religion, and not to the many time-bound laws evident in the earlier religious codes.

The message of Islam, so far from being "mad" or in any way peculiar, is eminently conformable to reason and the true facts of nature as created by Allah. It is the Truth in the purest sense of the term, and confirms the Message of all true Messengers that ever lived.
