They are asking thee concerning the Spirit. Say: The Spirit is by command of my Lord, and of knowledge ye have been vouchsafed but little. 85 Had We willed, We could take away what We have revealed to you, then you would find none to help you in recovering it from Us. 86 (It is naught) save mercy from thy Lord. Lo! His kindness unto thee was ever great. 87 Say thou: if the mankind and the jinn leagued together that they might produce the like of this Qur'an, they could nor produce the like thereof, though one to the other were a backer. 88 We have explained things for people in this Qur'an in diverse ways to make them understand the Message, yet most people obstinately persist in unbelief. 89 And they say: we shall by no means believe in thee until thou causest for us to gush forth from the earth a fountain. 90 or you have a garden of date palms and vines, and cause streams to flow plentifully in the midst of 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
