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 'Aleemum bimaa yaf'aloon
English Translation
And most of them follow not except assumption. Indeed, assumption avails not against the truth at all. Indeed, Allah is Knowing of what they do
