12 Preface وَمِن قَبلِهِ كِتابُ موسىٰ إِمامًا وَرَحمَةً ۚ وَهٰذا كِتابٌ مُصَدِّقٌ لِسانًا عَرَبِيًّا لِيُنذِرَ الَّذينَ ظَلَموا وَبُشرىٰ لِلمُحسِنينَYusuf AliAnd before this, was1 the Book of Moses as a guide and a mercy: And this Book confirms (it) in the Arabic tongue; to admonish the unjust, and as Glad Tidings to those who do right.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-ān 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.
