And they say, “We will not believe you until you cause to gush forth from the earth a spring for us, or [until] you have for you a garden of palm trees and grapes and make rivers gush forth within them abundantly, or you make the sky fall upon us in fragments as you have claimed, or you bring Allah and the angels before [us], or you have a house of ornament, or you ascend into the sky. And we will not believe in your ascension until you bring down to us a book we may read.” Say, “Glory be to the Lord! Was I ever but a human messenger?” And nothing prevented the people from believing when guidance came to them except that they said, “Has Allah sent a human messenger?” Say, “If there were angels walking upon the earth, settled and established, We would have sent down to them an angel (as a) messenger from heaven.” Say, “Sufficient is Allah as Witness between me and you. Indeed He is, concerning His servants, All-Aware and All-Seeing.”
