Ali 'Imran 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

Here you are - those who have argued about that of which you have [some] knowledge, but why do you argue about that of which you have no knowledge? And Allāh knows, while you know not.
