قُلْ يَا أَهْلَ الْكِتَابِ لَسْتُمْ عَلَىٰ شَيْءٍ حَتَّىٰ تُقِيمُوا التَّوْرَاةَ وَالْإِنجِيلَ وَمَا أُنزِلَ إِلَيْكُم مِّن رَّبِّكُمْ ۗ وَلَيَزِيدَنَّ كَثِيرًا مِّنْهُم مَّا أُنزِلَ إِلَيْكَ مِن رَّبِّكَ طُغْيَانًا وَكُفْرًا ۖ فَلَا تَأْسَ عَلَى الْقَوْمِ الْكَافِرِينَ (68)
(5:68) Say to them: 'People of the Book! You have no solid ground to stand on unless you establish the Torah and the Gospel and all that had been revealed to you from your Lord. *97 Indeed the message revealed to you from your Lord will aggravate insurgence and unbelief in many of them. *98 So do not grieve for those who disbelieve.
*97). By 'establishing the Torah and the Gospel' is meant observing them honestly and making them the law of life.
It should be noted here that the Scriptures which comprise the Bible consist of two kinds of writings. One was composed by the Jewish and Christian authors themselves. The second consists of those portions which have been recorded as either the injunctions of God or as the utterances of Moses, Jesus and other Prophets. Such portions are those in which it has been categorically stated that God said so and so, or that a particular Prophet said so and so. If we were to exclude the portions belonging to the first category and carefully study those belonging to the second we would notice that their teachings are not perceptibly different from those of the Qur'an. It is true that the second category has not altogether escaped the tamperings of translators, scribes and exegetes, and the errors of oral transmitters. Nevertheless, one cannot help feeling that the teachings embodied in the second category call man to the same pure monotheism as the Qur'an, that they propound those very beliefs propounded by the Qur'an and that they direct man to the same way of life as that to which the Qur'an seeks to direct him. Hence, had the Jews and the Christians adhered to the teaching attributed in their Scriptures to God and the Prophets they would certainly have become a truth-loving and truth-oriented group of people and would have been able to see in the Qur'an that very light which illuminates the earlier divine Scriptures. There would then have been no question of their abandoning their religion in order to follow the Prophet (peace be on him). To follow him would have caused neither break nor discontinuity; they would simply have gone one stage further along the same road.
*98). Instead of reflecting on this seriously and dispassionately, they were seized by a fit of intransigence which intensified their opposition.
