66 Preface ها أَنتُم هٰؤُلاءِ حاجَجتُم فيما لَكُم بِهِ عِلمٌ فَلِمَ تُحاجّونَ فيما لَيسَ لَكُم بِهِ عِلمٌ ۚ وَاللَّهُ يَعلَمُ وَأَنتُم لا تَعلَمونَYusuf AliAh! Ye are those who fell to disputing (Even) in matters of which ye had some knowledge1! but why dispute ye in matters of which ye have no knowledge? It is God Who knows, and ye who know not!The number of sects among the Jews and Christians shows that they wrangled and disputed even about some of the matters of their own religion, of which they should have had some knowledge. But when they talk of Father Abraham, they are entirely out of court, as he lived before their peculiar systems were evolved.
