They question you about the Spirit. Say, "The Spirit is at my Lord's command, and you have been granted but little knowledge." 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 But on account of mercy from your Lord-- surely His grace to you is abundant. 87 Say: Verily, though mankind and the jinn should assemble to produce the like of this Qur'an, they could not produce the like thereof though they were helpers one of another. 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 say: "We will not believe you until you make a spring of water gush forth from the earth for us; 90 Or, until you acquire an orchard of date-palm trees and grapes, and produce rivers flowing through it; 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 you have a house of adornable materials (like silver and pure gold, etc.), or you ascend up into the sky, and even then we will put no faith in your ascension until you bring down for us a Book that we would read." Say (O Muhammad SAW): "Glorified (and Exalted) be my Lord (Allah) above all that evil they (polytheists) associate with Him! Am I anything but a man, sent as a Messenger?" 93
