And they ask you, [O Muhammad], about the soul. Say, "The soul is of the affair of my Lord. And mankind have not been given of knowledge except a little." 85 And if We willed, We could surely do away with that which We revealed to you. Then you would not find for yourself concerning it an advocate against Us. 86 Except [We have left it with you] as a mercy from your Lord. Indeed, His favor upon you has ever been great. 87 Say thou: if the mankind and the jinn leagued together that they might produce the like of this Qur'an, they could nor produce the like thereof, though one to the other were a backer. 88 And We have certainly diversified for the people in this Qur'an from every [kind] of example, but most of the people refused [anything] except disbelief. 89 And they said, “We will not accept faith in you, until you cause a spring to gush forth from the earth for us.” 90 Or, until you acquire an orchard of date-palm trees and grapes, and produce rivers flowing through it; 91 Or thou causest the heaven to fall upon us, as thou assertest, in pieces, or thou bringest God and the angels face to face. 92 Or there be for thee a house of gold or thou mountest to the heaven, and we will by no means believe in thy mounting even until thou causest a book to be sent down to us, which we may read. Say thou: hallowed be my Lord! I am naught but a human being sent as an apostle. 93
