blind imitation (taqlid)

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

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?

أَوْ تَقُولُوٓا۟ إِنَّمَآ أَشْرَكَ ءَابَآؤُنَا مِن قَبْلُ وَكُنَّا ذُرِّيَّةً مِّنۢ بَعْدِهِمْ ۖ أَفَتُهْلِكُنَا بِمَا فَعَلَ ٱلْمُبْطِلُونَ

Or [lest] you say, "It was only that our fathers associated [others in worship] with Allāh before, and we were but descendants after them. Then would You destroy us for what the falsifiers have done?"

أَفَلَمْ يَدَّبَّرُوا۟ ٱلْقَوْلَ أَمْ جَآءَهُم مَّا لَمْ يَأْتِ ءَابَآءَهُمُ ٱلْأَوَّلِينَ

Then have they not reflected over the word [i.e., the Qur’ān], or has there come to them that which had not come to their forefathers?

قَالُوا۟ بَلْ وَجَدْنَآ ءَابَآءَنَا كَذَٰلِكَ يَفْعَلُونَ

They said, "But we found our fathers doing thus."
