They question you about the Spirit. Say, "The Spirit is at my Lord's command, and you have been granted but 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 by the mercy of your Lord. He has certainly bestowed great favors on you. 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 We have mentioned in this Quran all kinds of examples for the human being, but most human beings turn away in disbelief. 89 They declare, "We will never believe in you until you cause a spring to flow for us from the earth; 90 or, until you own a garden of palms and vines and cause rivers to gush forth with abundant water in them; 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 of gold or you ascend into the sky. And [even then], we will not believe in your ascension until you bring down to us a book we may read." Say, "Exalted is my Lord! Was I ever but a human messenger?" 93
