وَإِذَا قِيلَ لَهُمُ اتَّبِعُوا مَا أَنزَلَ اللَّهُ قَالُوا بَلْ نَتَّبِعُ مَا وَجَدْنَا عَلَيْهِ آبَاءنَا أَوَلَوْ كَانَ الشَّيْطَانُ يَدْعُوهُمْ إِلَى عَذَابِ السَّعِيرِ

And when it is said to them: “Follow that which Allah has sent down”, they say: “Nay, we shall follow that which we found our fathers (following).” (Would they do so) even if Shaitan (Satan) invites them to the torment of the Fire. 

(Luqman 31:21)
