They ask you about the Spirit. Say, "The Spirit comes by the command of my Lord. You have been given very little knowledge. 85 And if We willed We could surely take away that which We have revealed to you by inspiration (i.e. this Quran). Then you would find no protector for you against Us in that respect. 86 Except as a Mercy from your Lord. Verily! His Grace unto you (O Muhammad SAW) is ever great. 87 Say: 'If mankind and jinn combined together to produce the like of this Koran, they would never be able to produce one like it, not even if they were to help one another' 88 And indeed We have illustrated all kinds of examples in the Qur’an for mankind – so most men did not accept, except to be ungrateful. 89 They say, 'We will not believe thee till thou makest a spring to gush forth from the earth for us, 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
