وَإِذَا قِيلَ لَهُمُ اتَّبِعُوا مَا أَنزَلَ اللَّهُ قَالُوا بَلْ نَتَّبِعُ مَا وَجَدْنَا عَلَيْهِ آبَاءَنَا ۚ أَوَلَوْ كَانَ الشَّيْطَانُ يَدْعُوهُمْ إِلَىٰ عَذَابِ السَّعِيرِ (21)
(31:21) When they are told: 'Follow what Allah has revealed,' they say: 'We will rather follow that which we have found our forefathers following.' (Will they follow that) even though Satan might invite them to the chastisement of the Blazing Fire? *39
*39) That is, It is not at aII necessary that the forefathers of every person and every family and nation should have been on the right path. The mere argument that a particular way of life had been bequeathed by the elders cannot be a proof of its being right also. No sane person can commit the folly that he should blindly go on following the way of his forefathers even if they were not rightly guided, and should never bother to find out where the way is leading him."
