اٰل عمران — Ali 'Imran Ayat 66
هٰٓاَنْتُمْ هٰٓؤُلَاۤءِ حَاجَجْتُمْ فِيْمَا لَكُمْ بِهٖ عِلْمٌ فَلِمَ تُحَاۤجُّوْنَ فِيْمَا لَيْسَ لَكُمْ بِهٖ عِلْمٌ ۗ وَاللّٰهُ يَعْلَمُ وَاَنْتُمْ لَا تَعْلَمُوْنَ
Hā antum hā'ulā'i ḥājajtum fīmā lakum bihī ‘ilmun falima tuḥājjūna fīmā laisa lakum bihī ‘ilm(un), wallāhu ya‘lamu wa antum lā ta‘lamūn(a).
"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 Allah knows, while you know not."
