Tafsir of Surah Yunus 10:36
﴿وَمَا يَتَّبِعُ أَكْثَرُهُمْ إِلَّا ظَنًّا إِنَّ الظَّنَّ لَا يُغْنِي مِنَ الْحَقِّ شَيْئًا إِنَّ اللَّهَ عَلِيمٌ بِمَا يَفْعَلُونَ﴾
Translation of the meaning
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.
