Quran 3:66 Ali 'Imran, ayah 66 of 200

هَـٰٓأَنتُمْ هَـٰٓؤُلَآءِ حَـٰجَجْتُمْ فِيمَا لَكُم بِهِۦ عِلْمٌ فَلِمَ تُحَآجُّونَ فِيمَا لَيْسَ لَكُم بِهِۦ عِلْمٌ ۚ وَٱللَّهُ يَعْلَمُ وَأَنتُمْ لَا تَعْلَمُونَ ۝٦٦

3:66 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.
