6:156

أَن تَقُولُوا إِنَّمَا أُنزِلَ الْكِتَابُ عَلَىٰ طَائِفَتَيْنِ مِن قَبْلِنَا وَإِن كُنَّا عَن دِرَاسَتِهِمْ لَغَافِلِينَ

An taqooloo innama onzila alkitabu AAala ta-ifatayni min qablina wa-in kunna AAan dirasatihim laghafileena

Lest ye should say: "The Book was sent down to two Peoples before us, and for our part, we remained unacquainted with all that they learned by assiduous study:"

Lest ye should say: The Scripture was revealed only to two sects before us, and we in sooth were unaware of what they read;
