﴿أَنْ تَقُولُوا إِنَّمَا أُنْزِلَ الْكِتَابُ عَلَىٰ طَائِفَتَيْنِ مِنْ قَبْلِنَا وَإِنْ كُنَّا عَنْ دِرَاسَتِهِمْ لَغَافِلِينَ﴾
156. Lest you (pagan Arabs) should say: "The Book was sent down only to two sects before us (the Jews and the Christians), and for our part, we were in fact unaware of what they studied."
