3:66
هَـٰٓأَنتُمْ هَـٰٓؤُلَآءِ حَـٰجَجْتُمْ فِيمَا لَكُم بِهِۦ عِلْمٌ فَلِمَ تُحَآجُّونَ فِيمَا لَيْسَ لَكُم بِهِۦ عِلْمٌ ۚ وَٱللَّهُ يَعْلَمُ وَأَنتُمْ لَا تَعْلَمُونَ
hāantum hāulāi ḥājajtum fīmā lakum bihi ʿil'mun falima tuḥājjūna fīmā laysa lakum bihi ʿil'mun wal-lahu yaʿlamu wa-antum lā taʿlamūna
You argue about some things of which you have some knowledge, but why do you argue about things of which you know nothing? God knows and you do not.
Verily, you are those who have disputed about that of which you have knowledge. Why do you then dispute concerning that of which you have no knowledge? It is Allâh Who knows, and you know not.
