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 (Whatever you have received) is nothing but grace from your Lord. Indeed His favour to you is great. 87 Say: If men and jinn should combine together to bring the like of this Quran, they could not bring the like of it, though some of them were aiders of others. 88 We have mentioned in this Quran all kinds of examples for the human being, but most human beings turn away in disbelief. 89 They declare, "We will never believe in you until you cause a spring to flow for us from the earth; 90 or, until you own a garden of palms and vines and cause rivers to gush forth with abundant water in them; 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, until you possess an ornate house of gold, or ascend into the heavens; and we will not believe in your ascension until you have brought down for us a book which we can read' Say: 'Exaltations to my Lord! Am I anything except a human Messenger' 93
