They question you about the Spirit. Say, "The Spirit is at my Lord's command, and you have been granted but little knowledge." 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 Except as a Mercy from your Lord. Verily! His Grace unto you (O Muhammad SAW) is ever great. 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 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 say: "We will not believe you until you make a spring of water gush forth from the earth for us; 90 Or there be for thee a garden of date-palms and wine, and thou causest in the midst thereof rivers to gush forth. 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 you should have a house of gold, or you should ascend into heaven, and we will not believe in your ascending until you bring down to us a book which we may read. Say: Glory be to my Lord; am I aught but a mortal apostle? 93
