They ask you about revelation. Say, revelation is by the command of your Lord, and that you have been given 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 [Thou art spared] only by thy Sustainer's grace: behold, His favour towards thee 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 Indeed, We have set forth for mankind in this Koran every kind of parable, yet most people refuse all except disbelief. 89 They say, 'We will not believe thee till thou makest a spring to gush forth from the earth for us, 90 or, until you own a garden of palms and vines and cause rivers to gush forth with abundant water in them; 91 “Or you cause the sky to fall upon us in pieces like you said – or bring Allah and the angels as Witness.” 92 Or there be for thee a house of gold or thou mountest to the heaven, and we will by no means believe in thy mounting even until thou causest a book to be sent down to us, which we may read. Say thou: hallowed be my Lord! I am naught but a human being sent as an apostle. 93
