Aal-'Imran - 3:66

هَاأَنتُمْ هَؤُلاء حَاجَجْتُمْ فِيمَا لَكُم بِهِ عِلمٌ فَلِمَ تُحَآجُّونَ فِيمَا لَيْسَ لَكُم بِهِ عِلْمٌ وَاللّهُ يَعْلَمُ وَأَنتُمْ لاَ تَعْلَمُونَ
[3:66]
Behold! you are they who disputed about that of which you had knowledge; why then do you dispute about that of which you have no knowledge? And Allah knows while you do not know.
Ah! Ye are those who fell to disputing (Even) in matters of which ye had some knowledge! but why dispute ye in matters of which ye have no knowledge? It is Allah Who knows, and ye who know not!
Lo! ye are those who argue about that whereof ye have some knowledge: Why then argue ye concerning that whereof ye have no knowledge? Allah knoweth. Ye know not.
