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 please, We should certainly take away that which We have revealed to you, then you would not find for it any protector against Us. 86 Except for Mercy from thy Lord: for his bounty is to thee (indeed) great. 87 Say: "If the mankind and the jinns were together to produce the like of this Quran, they could not produce the like thereof, even if they helped one another." 88 In this Quran, We have set out all kinds of examples for people, yet most of them persist in denying the truth. 89 And say: "We will not believe you until you make a spring of water gush forth from the earth for us; 90 or you (show) us that you have your own garden of palm trees and vines with flowing streams therein, 91 or thou cause the skies to fall down upon us in smithereens, as thou hast threatened, or [till] thou bring God and the angels face to face before us, 92 or (show us) that you have a well adorned house of your own, or climb into the sky. We shall never believe that you have climbed into the sky until you bring us a book that we can read." Say, "All glory belongs to my Lord. Am I more than a mortal Messenger?" 93
