Surah Al-An'am — Ayah 156 (6:156)
أَن تَقُولُوٓاْ إِنَّمَآ أُنزِلَ ٱلۡكِتَٰبُ عَلَىٰ طَآئِفَتَيۡنِ مِن قَبۡلِنَا وَإِن كُنَّا عَن دِرَاسَتِهِمۡ لَغَٰفِلِينَ ١٥٦
English translation (Saheeh International)
[We revealed it] lest you say, "The Scripture was only sent down to two groups before us, but we were of their study unaware,"
Brief commentary
This Book was revealed so that you, idolaters, do not say: Allah only revealed the Torah and the Gospel to the Jews and the Christians before us and He did not reveal any scripture to us. I do not know how to read their scriptures as they are in their language and not in ours.
