قُلْ يَٰٓأَهْلَ ٱلْكِتَٰبِ لَسْتُمْ عَلَىٰ شَىْءٍ حَتَّىٰ تُقِيمُوا۟ ٱلتَّوْرَىٰةَ وَٱلْإِنجِيلَ وَمَآ أُنزِلَ إِلَيْكُم مِّن رَّبِّكُمْ ۗ وَلَيَزِيدَنَّ كَثِيرًۭا مِّنْهُم مَّآ أُنزِلَ إِلَيْكَ مِن رَّبِّكَ طُغْيَٰنًۭا وَكُفْرًۭا ۖ فَلَا تَأْسَ عَلَى ٱلْقَوْمِ ٱلْكَٰفِرِينَ
Say O People of the Scripture! Ye have naught (of guidance) till ye observe the Torah and the Gospel and that which was revealed unto you from your Lord. That which is revealed unto thee (Muhammad) from thy Lord is certain to increase the contumacy and disbelief of many of them. But grieve not for the disbelieving folk.
Surah Al-Maaida(5:68)
