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
(You may no longer) say now that the Book was revealed only to two groups of people before Us and that we had indeed been unaware of what they read.
