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 Had We willed, We could take away what We have revealed to you, then you would find none to help you in recovering it from Us. 86 Except as a mercy from thy Lord verily His grace unto thee is ever great. 87 Say: "If the whole of mankind and Jinns were to gather together to produce the like of this Qur'an, they could not produce the like thereof, even if they backed up each other with help and support. 88 And indeed We have fully explained to mankind, in this Quran, every kind of similitude, but most mankind refuse (the truth and accept nothing) but disbelief. 89 They have said, "We shall never believe you until you cause a spring to gush forth from the earth, 90 Or, until you acquire an orchard of date-palm trees and grapes, and produce rivers flowing through it; 91 Or, let chunks of sky fall over us, as you assert (you will); or, bring God and the angels as a surety; 92 or that there come to be for you a house of gold, or that you ascend to the sky - though we shall not believe in your ascension (to the sky) - until you bring down a book for us that we can read." Say to them, (O Muhammad): "Holy is my Lord! Am I anything else than a human being, who bears a Message (from Allah)?" 93
