They question you about the Spirit. Say, "The Spirit is at my Lord's command, and you have been granted but little knowledge." 85 And if We willed, We could surely do away with that which We revealed to you. Then you would not find for yourself concerning it an advocate against Us. 86 except through the special mercy of your Lord. His favours towards you has been great indeed. 87 Say, "If all human beings and jinn were to come together to bring the equivalent of this Quran, they could not do so, even if they all were to help each other. 88 In this Quran, We have set out all kinds of examples for people, yet most of them persist in denying the truth. 89 They say, 'We will not believe thee till thou makest 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 cause the sky to fall on us in pieces as you claimed, or bring Allah 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
