*46). The fact that Jesus preached the same religion as that expounded earlier by Moses and the other Prophets is also borne out by the statements of the existing Gospels: According to Matthew, in his Sermon on the Mount the Messiah categorically declared: 'Think not that I have come to abolish the law and the prophets; I have come not to abolish them but to fulfil them' (Matthew 5: 17). And when a Jewish lawyer enquired: 'Teacher, which is the greatest commandment in the Law?', Jesus replied: 'You shall love the Lord your God with all your heart, and with all your soul, and with all your mind. This is the greatest and the first commandment. And a second is like it, you shall love your neighbour as yourself. On these two commandments depends the law and the prophets' (ibid., 22: 37-40). He also instructed his disciples: The scribes and the Pharisees sit on Moses' seat, so practise and observe whatever they tell you, but not what they do; for they preach, but do not practise' (ibid., 23: 2-3).
*47). What Jesus wanted to impress upon them was that he would abolish the prohibitive innovations which had infiltrated the original Divine Law (Shari'ah}. These were the results of the superstitions of their ignorant commoners, the legal hair-splitting of their lawyers, the extremism of their world-renouncing pietists, and the ascendancy and predominance of non-Muslim peoples over them. In determining what is lawful and unlawful, Jesus would be guided by the injunctions of God and not by the inventions of human beings.
