blind following of ancestors

قَالُوا۟ يَـٰصَـٰلِحُ قَدْ كُنتَ فِينَا مَرْجُوًّا قَبْلَ هَـٰذَآ ۖ أَتَنْهَىٰنَآ أَن نَّعْبُدَ مَا يَعْبُدُ ءَابَآؤُنَا وَإِنَّنَا لَفِى شَكٍّ مِّمَّا تَدْعُونَآ إِلَيْهِ مُرِيبٍ

They said, "O Ṣāliḥ, you were among us a man of promise before this. Do you forbid us to worship what our fathers worshipped? And indeed we are, about that to which you invite us, in disquieting doubt."

مَّا لَهُم بِهِۦ مِنْ عِلْمٍ وَلَا لِـَٔابَآئِهِمْ ۚ كَبُرَتْ كَلِمَةً تَخْرُجُ مِنْ أَفْوَٰهِهِمْ ۚ إِن يَقُولُونَ إِلَّا كَذِبًا

They have no knowledge of it, nor had their fathers. Grave is the word that comes out of their mouths; they speak not except a lie.

لَقَدْ وُعِدْنَا نَحْنُ وَءَابَآؤُنَا هَـٰذَا مِن قَبْلُ إِنْ هَـٰذَآ إِلَّآ أَسَـٰطِيرُ ٱلْأَوَّلِينَ

We have been promised this, we and our forefathers, before; this is not but legends of the former peoples."

قَالُوا۟ نَعْبُدُ أَصْنَامًا فَنَظَلُّ لَهَا عَـٰكِفِينَ

They said, "We worship idols and remain to them devoted."

إِنَّهُمْ أَلْفَوْا۟ ءَابَآءَهُمْ ضَآلِّينَ

Indeed they found their fathers astray.

أَمْ ءَاتَيْنَـٰهُمْ كِتَـٰبًا مِّن قَبْلِهِۦ فَهُم بِهِۦ مُسْتَمْسِكُونَ

Or have We given them a book before it [i.e., the Qur’ān] to which they are adhering?

وَإِذَا تُتْلَىٰ عَلَيْهِمْ ءَايَـٰتُنَا بَيِّنَـٰتٍ مَّا كَانَ حُجَّتَهُمْ إِلَّآ أَن قَالُوا۟ ٱئْتُوا۟ بِـَٔابَآئِنَآ إِن كُنتُمْ صَـٰدِقِينَ

And when Our verses are recited to them as clear evidences, their argument is only that they say, "Bring [back] our forefathers, if you should be truthful."
