Islam first came before the world as a doubly totalitarian system. It claimed to impose itself on the whole world and it claimed also, by the divinely appointed Muhammadan law, by the principles of the fiqh, to regulate down to the smallest details the whole life of the Islamic community and of every individual believer. ... [T]he study of Muhammadan law (dry and forbidding though it may appear to those who confine themselves to the indispensable study of the fiqh) is of great importance to the world today.
