They question you about the spirit. Say: 'The spirit is from the command of my Lord. Except for a little knowledge you have been given nothing' 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 excepting by some mercy of thy Lord; surly His favour to thee is great. 87 Say: 'If mankind and jinn combined together to produce the like of this Koran, they would never be able to produce one like it, not even if they were to help 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 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, let chunks of sky fall over us, as you assert (you will); or, bring God and the angels as a surety; 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
