يونس — Yunus Ayat 36
وَمَا يَتَّبِعُ اَكْثَرُهُمْ اِلَّا ظَنًّاۗ اِنَّ الظَّنَّ لَا يُغْنِيْ مِنَ الْحَقِّ شَيْـًٔاۗ اِنَّ اللّٰهَ عَلِيْمٌ ۢبِمَا يَفْعَلُوْنَ
Wa mā yattabi‘u akṡaruhum illā ẓannā(n), innaẓ-ẓanna lā yugnī minal-ḥaqqi syai'ā(n), innallāha ‘alīmum bimā yaf‘alūn(a).
"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."
