They ask you about revelation. Say, revelation is by the command of your Lord, and that you have been given but little knowledge. 85 If We pleased We could take away what We have revealed to you. Then you will not find any one to plead for it with 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 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 indeed turned about for men in this Koran every manner of similitude; yet most men refuse all but unbelief. 89 They say: 'We will not believe in you until you make a spring gush 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 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, you come to possess a house of gold; or ascend to the skies, though we shall not believe in your having ascended till you bring down a book for us which we could read." Say: "Glory to my Lord. I am only man and a messenger." 93
