هٰٓاَنْتُمْ هٰٓؤُلَاۤءِ حَاجَجْتُمْ فِيْمَا لَكُمْ بِهٖ عِلْمٌ فَلِمَ تُحَاۤجُّوْنَ فِيْمَا لَيْسَ لَكُمْ بِهٖ عِلْمٌ ۗ وَاللّٰهُ يَعْلَمُ واَنْتُمْ لَا تَعْلَمُوْنَ ( آل عمران: ٦٦ )
Haaa antum haaa'ulaaa'i baajajtum feemaa lakum bihee 'ilmun falima tuhaaajjoonaa feemaa laisa lakum bihee 'ilm; wallaahu ya'lamu wa antum laa ta'lamoon (ʾĀl ʿImrān 3:66)
Sahih International:
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. (Ali 'Imran [3] : 66)
1 Mufti Taqi Usmani
Look, this is what you are - you have already argued about matters concerning which you have knowledge; why then do you argue about matters of which you have no knowledge? Allah knows and you do not know.
