Verse 170

وَإِذَا قِيلَ لَهُمُ ٱتَّبِعُوا۟ مَآ أَنزَلَ ٱللَّهُ قَالُوا۟ بَلْ نَتَّبِعُ مَآ أَلْفَيْنَا عَلَيْهِ ءَابَآءَنَآ أَوَلَوْ كَانَ ءَابَآؤُهُمْ لَا يَعْقِلُونَ شَيْـًٔا وَلَا يَهْتَدُونَ

And when they are told to follow what God has revealed, they say, on the contrary we follow what we found our forefathers did. What if their forefathers did not understand a thing nor were they guided?
