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 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 your Lord; for His favor to you is great indeed. 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 they say: "We shall not believe in you (O Muhammad SAW), until you cause a spring to gush forth from the earth for us; 90 or that there be a garden of palms and vines for you and then you cause rivers to abundantly flow forth through them; 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
