Al-Maaida 5:104
وَإِذَا قِيلَ لَهُمْ تَعَالَوْا۟ إِلَىٰ مَآ أَنزَلَ ٱللَّهُ وَإِلَى ٱلرَّسُولِ قَالُوا۟ حَسْبُنَا مَا وَجَدْنَا عَلَيْهِ ءَابَآءَنَآ ۚ أَوَلَوْ كَانَ ءَابَآؤُهُمْ لَا يَعْلَمُونَ شَيْـًٔا وَلَا يَهْتَدُونَ
When it is said to them, “Come to what Allah has sent down, and to the Messenger;” they say, “Sufficient for us is that on which we have found our forefathers.” Is it so, even though their forefathers knew nothing, and had no guidance either?
