And they ask thee regarding the spirit; say thou: the spirit is by the command of my Lord, and ye have not been vouchsafed of knowledge save a little. 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: "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 For, indeed, many facets have We given in this Qur'an to every kind of lesson [designed] for [the benefit of] mankind! However, most men are unwilling to accept anything but blasphemy 89 They say: 'We will not believe in you until you make a spring gush from the earth for us, 90 “Or you have a garden of date-palms and grapes, and you make gushing rivers to flow in 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, 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
