What are the ayat sent for cultural Muslims?

Allah says:

وَإِذَا قِيلَ لَهُمۡ تَعَالَوۡاْ إِلَىٰ مَآ أَنزَلَ ٱللَّهُ وَإِلَى ٱلرَّسُولِ قَالُواْ حَسۡبُنَا مَا وَجَدۡنَا عَلَيۡهِ ءَابَآءَنَآ‌ۚ أَوَلَوۡ كَانَ ءَابَآؤُهُمۡ لَا يَعۡلَمُونَ شَيۡـًٔ۬ا وَلَا يَہۡتَدُونَ 

And when it is said to them, "Come to what Allah 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? [1]

The above revelation was made when Prophet Muhammad (ﷺ) advised the people to worship only one God, to give up the false gods, etc. Their response was, we must hold on to our cultural norms.
