6:156
أَن تَقُولُوٓا۟ إِنَّمَآ أُنزِلَ ٱلْكِتَٰبُ عَلَىٰ طَآئِفَتَيْنِ مِن قَبْلِنَا وَإِن كُنَّا عَن دِرَاسَتِهِمْ لَغَٰفِلِينَ
An taqooloo innammaaa unzilal Kitaabu 'alaa taaa'ifataini min qablinaa wa in kunnaa 'an diraasatihim laghaafileen
Lest you say that the Book was only revealed to two parties before us and We were truly unaware of what they read.
