They will question thee concerning the Spirit. Say: 'The Spirit is of the bidding of my Lord. You have been given of knowledge nothing except a little.' 85 And if We please, We should certainly take away that which We have revealed to you, then you would not find for it any protector against Us. 86 except for Mercy from your Lord; for His favor to you is great indeed. 87 Say: 'If men and jinn banded together to produce the like of this Koran, they would never produce its like, not though they backed one another.' 88 And verily We have displayed for mankind in this Qur'an all kind of similitudes, but most of mankind refuse aught save disbelief. 89 And they say, "We will not believe you until you break open for us from the ground a spring. 90 or you (show) us that you have your own garden of palm trees and vines with flowing streams therein, 91 or cause the sky to fall on us in pieces as you claimed, or bring Allah and the angels before us, face to face; 92 or you have a house made of gold; or you ascend to heaven; and we will not believe in your ascension until you send down to us a Book that we can read." Tell them, "Holy is my Lord. I am but a human being sent as a messenger." 93
