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 If We pleased, We would certainly take away that which We have revealed to you, then you would find no guardian for you against Us, 86 excepting by some mercy of thy Lord; surly His favour to thee is great. 87 Say, "If mankind and the jinn gathered in order to produce the like of this Qur'an, they could not produce the like of it, even if they were to each other assistants." 88 We have indeed turned about for men in this Koran every manner of similitude; yet most men refuse all but unbelief. 89 They declare, "We will never believe in you until you cause a spring to flow for us from the earth; 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, 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 that there come to be for you a house of gold, or that you ascend to the sky - though we shall not believe in your ascension (to the sky) - until you bring down a book for us that we can read." Say to them, (O Muhammad): "Holy is my Lord! Am I anything else than a human being, who bears a Message (from Allah)?" 93
