And they ask you about the soul. Say: The soul is one of the commands of my Lord, and you are not given aught of knowledge but a little. 85 And if We willed We could have taken away the revelations which We have sent to you – you would then not find anyone who could advocate for you before Us for this. 86 Except for Mercy from thy Lord: for his bounty is to thee (indeed) 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 In this Quran, We have set out all kinds of examples for people, yet most of them persist in denying the truth. 89 and so they say: "[O Muhammad,] we shall not believe thee till thou cause a spring to gush forth for us from the earth, 90 Or, until you acquire an orchard of date-palm trees and grapes, and produce rivers flowing through it; 91 or till thou makest heaven to fall, as thou assertest, on us in fragments, or thou bringest God and the angels as a surety, 92 Or thou have a house of gold; or thou ascend up into heaven, and even then we will put no faith in thine ascension till thou bring down for us a book that we can read. Say (O Muhammad): My Lord be Glorified! Am I aught save a mortal messenger? 93
