156أَن تَقولوا إِنَّما أُنزِلَ الكِتابُ عَلىٰ طائِفَتَينِ مِن قَبلِنا وَإِن كُنّا عَن دِراسَتِهِم لَغافِلينَ(Irfan-ul-Quran)(The Qur’an has been revealed lest) you (should) say: ‘The (heavenly) Book was sent down before us only to the two communities (the Jews and the Christians), and undoubtedly we were unaware of their reading and teaching.’
