They ask you about the Spirit. Say, "The Spirit comes by the command of my Lord. You have been given very little knowledge. 85 And if We please, We should certainly take away that which We have revealed to you, then you would not find for it any protector against Us. 86 except by the mercy of your Lord. He has certainly bestowed great favors on you. 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 In this Quran, We have set out all kinds of examples for people, yet most of them persist in denying the truth. 89 They say: "We shall not believe in thee, until thou cause a spring to gush forth for us from the earth, 90 "Or (until) thou have a garden of date trees and vines, and cause rivers to gush forth in their midst, carrying abundant water; 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 you have a house made of gold; or you ascend to heaven; and we will not believe in your ascension until you send down to us a Book that we can read." Tell them, "Holy is my Lord. I am but a human being sent as a messenger." 93
