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 And if We listed, We could surely take away that which We have revealed unto thee; then thou wilt not find in respect thereof against Us as trustee. 86 except through the special mercy of your Lord. His favours towards you has been great indeed. 87 Say: "Surely, if mankind and jinn were to get together to produce the like of this Qur'an, they will never be able to produce the like of it, howsoever they might help one another." 88 We have given examples of every kind to men in this Qur'an in various ways, and even then most men disdain everything but unbelief, 89 They say: 'We will not believe in you until you make a spring gush from the earth for us, 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 thou cause the skies to fall down upon us in smithereens, as thou hast threatened, or [till] thou bring God and the angels face to face before us, 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
