Qur'an 5:104 · Al-Maaida

وَإِذَا قِيلَ لَهُمْ تَعَالَوْا۟ إِلَىٰ مَآ أَنزَلَ ٱللَّهُ وَإِلَى ٱلرَّسُولِ قَالُوا۟ حَسْبُنَا مَا وَجَدْنَا عَلَيْهِ ءَابَآءَنَآ ۚ أَوَلَوْ كَانَ ءَابَآؤُهُمْ لَا يَعْلَمُونَ شَيْـًۭٔا وَلَا يَهْتَدُونَ

(104) And when it is said to them, "Come to what Allāh has revealed and to the Messenger," they say, "Sufficient for us is that upon which we found our fathers." Even though their fathers knew nothing, nor were they guided?
