And they ask you (O Muhammad SAW) concerning the Ruh (the Spirit); Say: "The Ruh (the Spirit): it is one of the things, the knowledge of which is only with my Lord. And of knowledge, you (mankind) have been given only a little." 85 Had We wanted, We could have removed the Spirit through whom We sent you revelation. Then you would not have found anyone to intercede with Us for you 86 [Thou art spared] only by thy Sustainer's grace: behold, His favour towards thee is great indeed! 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 given examples of every kind to men in this Qur'an in various ways, and even then most men disdain everything but unbelief, 89 And they say: We will not put faith in thee till thou cause a spring to 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 you cause the heavens to fall down on us in pieces, as you have claimed; or you bring God and the angels before us face to face; 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
