وَمَا يَتَّبِعُ أَكۡثَرُهُمۡ إِلَّا ظَنًّاۚ إِنَّ ٱلظَّنَّ لَا يُغۡنِي مِنَ ٱلۡحَقِّ شَيۡـًٔاۚ إِنَّ ٱللَّهَ عَلِيمُۢ بِمَا يَفۡعَلُونَ

Wa maa yattabi'u aksaruhum illaa zannaa; innaz zanna laa yughnee minal haqqi shai'aa; innal laaha 'Aleemun bimaa yaf'aloon

But most of them follow nothing but fancy: truly fancy can be of no avail against truth. Verily Allah is well aware of all that they do.

— Yunus (يُونُس), 10:36
