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 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 But on account of mercy from your Lord-- surely His grace to you is abundant. 87 Say, "If all human beings and jinn were to come together to bring the equivalent of this Quran, they could not do so, even if they all were to help each other. 88 We have indeed turned about for men in this Koran every manner of similitude; yet most men refuse all but unbelief. 89 They have said, "We shall never believe you until you cause a spring to gush forth from the earth, 90 “Or you have a garden of date-palms and grapes, and you make gushing rivers to flow in it.” 91 "Or you cause the heaven to fall upon us in pieces, as you have pretended, or you 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
