Yunus 36

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

wamā yattabiʿu aktharuhum illā ẓannan inna l-ẓana lā yugh'nī mina l-ḥaqi shayan inna l-laha ʿalīmun bimā yafʿalūna

And most of them follow not except assumption. Indeed, assumption avails not against the truth at all. Indeed, Allāh is Knowing of what they do.
