Al-'Imran (The Family of Imran)

Surah 3 · Verse 66

Yes, you are those who disputed about that of which you had knowledge but why do you dispute about that of which you have no knowledge? And Allah knows and you do not know.

هَا أَنْتُمْ هَٰؤُلَاءِ حَاجَجْتُمْ فِيمَا لَكُمْ بِهِ عِلْمٌ فَلِمَ تُحَاجُّونَ فِيمَا لَيْسَ لَكُمْ بِهِ عِلْمٌ ۚ وَاللَّهُ يَعْلَمُ وَأَنْتُمْ لَا تَعْلَمُونَ
