Sc., in its original, uncorrupted form.
The last revealed Book which was a Code of Life (Shari'at) 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. v. 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'at became necessary, and this was provided in Islam.
