They question you about the Spirit. Say, "The Spirit is at my Lord's command, and you have been granted but little knowledge." 85 If it were Our Will, We could take away that which We have sent thee by inspiration: then wouldst thou find none to plead thy affair in that matter as against Us,- 86 (It is naught) save mercy from thy Lord. Lo! His kindness unto thee was ever great. 87 Say, "If all men and jinn gathered together to produce the like of this Quran, they could not produce one like it, however much they helped one another." 88 Indeed, We have set forth for mankind in this Koran every kind of parable, yet most people refuse all except disbelief. 89 And say: "We will not believe you until you make a spring of water gush forth from the earth for us; 90 or you (show) us that you have your own garden of palm trees and vines with flowing streams therein, 91 or, until you cause the sky to fall upon us in pieces, as you have claimed, or, as a surety bring Allah with the angels in front; 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
