So that the people of the Scripture (Jews and Christians) may know that they have no power whatsoever over the Grace of Allah, and that (His) Grace is (entirely) in His Hand to bestow it on whomsoever He wills. And Allah is the Owner of Great Bounty.
[This is] so that the People of the Scripture may know that they are not able [to obtain] anything from the bounty of Allah and that [all] bounty is in the hand of Allah; He gives it to whom He wills. And Allah is the possessor of great bounty.
(57:29) (You should do this) so that the People of the Book know that they have no control over Allah's Bounty, and that all bounty is in Allah's Hand; He bestows it on whomsoever He pleases. Allah is the Lord of abounding bounty.
