Almuntakhab Fi Tafsir Alquran Alkarim

Yet they lack the knowledge giving firm belief of what is true on sufficient grounds, and they follow an emotion, they imagine, will direct them to the attainment and possession of the object from which, in their view, satisfaction is expected. But never does an unverified supposition or an opinion offered on insufficient presumptive evidence replace the truth or conformity with fact

And they have thereof no knowledge. They follow not except assumption, and meaning

*23) That is, "They have not adopted this creed about the angels on the ground that they had found through some means of knowledge that they were females and daughters of God, but they have presumed this on mere conjecture and have set up these shrines at which they pray for fulfillment of desires, make offerings and pay tributes."
