They will question thee concerning the Spirit. Say: 'The Spirit is of the bidding of my Lord. You have been given of knowledge nothing except a little.' 85 And if We listed, We could surely take away that which We have revealed unto thee; then thou wilt not find in respect thereof against Us as trustee. 86 except for Mercy from your Lord; for His favor to you is great indeed. 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 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 And they say, "We will not believe you until you break open for us from the ground a spring. 90 "Or (until) thou have a garden of date trees and vines, and cause rivers to gush forth in their midst, carrying abundant water; 91 Or you should cause the heaven to come down upon us in pieces as you think, or bring Allah and the angels face to face (with 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
