They did not appraise Allah with true appraisal

{ And they did not appraise Allah with true appraisal when they said, " Allah did not reveal to a human being anything." Say, "Who revealed the Scripture that Moses brought as light and guidance to the people? You [Jews] make it into pages, disclosing [some of] it and concealing much. And you were taught that which you knew not - neither you nor your fathers." Say, " Allah [revealed it]." Then leave them in their [empty] discourse, amusing themselves. }
