And they ask thee regarding the spirit; say thou: the spirit is by the command of my Lord, and ye have not been vouchsafed of knowledge save a little. 85 And if We so willed, We could indeed take away whatever We have revealed unto thee, and in that [state of need] thou wouldst find none to plead in thy behalf before Us. 86 except for Mercy from your Lord; for His favor to you is great indeed. 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 And say: "We will not believe you until you make a spring of water gush forth from the earth for us; 90 "Or you have a garden of date-palms and grapes, and cause rivers to gush forth in their midst abundantly; 91 "Or you cause the heaven to fall upon us in pieces, as you have pretended, or you bring Allah 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
