And they do not assign to Allah the attributes due to Him when they say: Allah has not revealed anything to a mortal. Say: Who revealed the Book which Musa brought, a light and a guidance to men, which you make into scattered writings which you show while you conceal much? And you were taught what you did not know, (neither) you nor your fathers. Say: Allah then leave them sporting in their vain discourses.

So that the followers of the Book may know that they do not control aught of the grace of Allah, and that grace is in Allah's hand, He gives it to whom He pleases; and Allah is the Lord of mighty grace.
