The message taught by the Prophet Muhammad was exactly the same as had been taught by Abraham. But those People of the Book, who prided themselves on being followers of Abraham, led the opposition against the Prophet. Why did they act in this manner? The reason was that the religion that the Prophet taught, and which Abraham had taught before him, was the religion of Islam. Now, Islam means total submission to God, and it was this religion that Abraham handed down to his offspring. But the religion that the People of the Book practised had nothing to do with total submission to God. Having lapsed into permissiveness and, unwilling to change this lifestyle, they had allowed their religion to degenerate into a series of hollow rituals, which they fondly believed would make it easy for them to enter paradise. In the religion that the Prophet Muhammad taught, however, one could gain salvation only by virtue of one’s actions. The People of the Book, for their part, thought that their affiliation to a nation of saints and prophets would be sufficient to earn them redemption. There was a world of difference then between Islam, the true religion of Abraham, and the religion that the People of the Book practised and attributed to him. True religion means acceptance of divine guidance, as revealed to man through the prophets, whereas the religion practised by the People of the Book was based on their own national legacy, a collection of national traditions, which had accumulated over generations.
