Surah Al-An'am (The Cattle), Verse 156

اَنْ تَقُوْلُوْۤا اِنَّمَاۤ اُنْزِلَ الْكِتٰبُ عَلٰی طَآىِٕفَتَیْنِ مِنْ قَبْلِنَا وَاِنْ كُنَّا عَنْ دِرَاسَتِهِمْ لَغٰفِلِیْنَ ۟

An taqooloo inna maaa unzilal Kitaabu 'alaa taaa'ifataini min qablinaa wa in kunnaa 'an diraasatihim laghaafileen

“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:"”
