4786 The last revealed Book which was a Code of Life ( Shari 'ah) was the Book of Moses: for that of Jesus was not such a Code, but merely moral precepts to sweep away the corruptions that had crept in. The Qur'an has the same attitude to it as the teaching of Jesus had to the Law. Jesus said (Matt.
5:17 ): "Think not that I am come to destroy the Law or the prophets; I am not come to destroy, but to fulfil," But the corruptions took new forms in Christian Churches : an entirely new Shari 'ah became necessary, and this was provided in Islam.
