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 have taken away the revelations which We have sent to you – you would then not find anyone who could advocate for you before Us for this. 86 Except the mercy of your Lord; indeed His munificence upon you (O dear Prophet Mohammed – peace and blessings be upon him) is extremely great. 87 Say, "If all men and jinn gathered together to produce the like of this Quran, they could not produce one like it, however much they helped one another." 88 Indeed, We have set forth for mankind in this Koran every kind of parable, yet most people refuse all except disbelief. 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 cause rivers to gush forth in their midst abundantly; 91 Or you make the heaven fall upon us in fragments as you have claimed or you bring Allah and the angels before [us] 92 or, until you possess an ornate house of gold, or ascend into the heavens; and we will not believe in your ascension until you have brought down for us a book which we can read' Say: 'Exaltations to my Lord! Am I anything except a human Messenger' 93
