Surat Yunus (Jonas) - يونس

وَمَا يَتَّبِعُ أَكْثَرُهُمْ إِلَّا ظَنًّا إِنَّ ٱلظَّنَّ لَا يُغْنِى مِنَ ٱلْحَقِّ شَيْـًٔا إِنَّ ٱللَّهَ عَلِيمٌۢ بِمَا يَفْعَلُونَ ﴿٣٦﴾

And most of them do not follow (anything) but conjecture; surely conjecture will not avail aught against the truth; surely Allah is cognizant of what they do.
