They ask you about the Spirit. Say, "The Spirit comes by the command of my Lord. You have been given very little knowledge. 85 If We pleased, We would certainly take away that which We have revealed to you, then you would find no guardian for you 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, "If all men and jinn gathered together to produce the like of this Quran, they could not produce one like it, however much they helped one another." 88 We have mentioned in this Quran all kinds of examples for the human being, but most human beings turn away in 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 you (show) us that you have your own garden of palm trees and vines with flowing streams therein, 91 or you cause the heavens to fall down on us in pieces, as you have claimed; or you bring God and the angels before us face to face; 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
