Surah Ali 'Imran — Ayah 66 (3:66)
هَٰٓأَنتُمۡ هَٰٓؤُلَآءِ حَٰجَجۡتُمۡ فِيمَا لَكُم بِهِۦ عِلۡمٞ فَلِمَ تُحَآجُّونَ فِيمَا لَيۡسَ لَكُم بِهِۦ عِلۡمٞۚ وَٱللَّهُ يَعۡلَمُ وَأَنتُمۡ لَا تَعۡلَمُونَ ٦٦
English translation (Saheeh 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 Allāh knows, while you know not.
Brief commentary
You, People of the Scripture, argued without knowledge with the Prophet (peace be upon him) about your religion and about what was revealed to you. Why, then, do you dispute about Abraham and his religion, which you do not know, as it is not in your book and your prophets did not discuss it? Allah knows the reality of things and you do not know.
