hā-ʾantum hāʾulāʾi ḥājajtum fī-mā lakum bihī ʿilmun fa-li-ma tuḥājjūna fī-mā laysa lakum bihī ʿilmun wa-llāhu yaʿlamu wa-ʾantum lā taʿlamūna
Ah! You are the very ones who argue about that of which you have knowledge. But why do you argue about that of which you have no knowledge? And Allah knows and you do not know.
— Ali Quli Qarai
Surah 'Ali-Imran, Verse 66
66. "Ha, you are those who disputed about that of which you had knowledge; why then do you dispute about that of which you have no knowledge? Surely Allah knows, and you know not."
This verse is both a reminder and a warning to the People of the Book. It tells them that they raised objections and asked some inappropriate questions upon what they knew. For instance at that time, they observed the natural life of Jesus (as) with their own eyes, and saw -his material needs: his need to food, his need to clothing, and his need to residence, yet they disputed about him. Some of them called him (as) a liar and some others considered him Son of God! Or, they disputed about Muhammad (S) whose tokens were clearly cited in the Torah and Evangel and they were known to them.2
When you can not find a definite point and dispute upon what you know, why do you refer to a phenomenon that you have not knowledge about it and, for example, you seek for the religion of Abraham (as)?
This is because Allah knows everything but you do not. (Then you should learn it from the concerned ones, viz. from the Prophet (S) and his book.)
