They ask you about revelation. Say, revelation is by the command of your Lord, and that you have been given 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 [We have left it with you] as a mercy from your Lord. Indeed, His favor upon you has ever been great. 87 Say: "Surely, if mankind and jinn were to get together to produce the like of this Qur'an, they will never be able to produce the like of it, howsoever they might help one another." 88 We have indeed turned about for men in this Koran every manner of similitude; yet most men refuse all but unbelief. 89 They say: "We shall not believe in thee, until thou cause a spring to gush forth for us 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 thou causest the heaven to fall upon us, as thou assertest, in pieces, or thou bringest God and the angels face to face. 92 "Or you have a house of adornable materials (like silver and pure gold, etc.), or you ascend up into the sky, and even then we will put no faith in your ascension until you bring down for us a Book that we would read." Say (O Muhammad SAW): "Glorified (and Exalted) be my Lord (Allah) above all that evil they (polytheists) associate with Him! Am I anything but a man, sent as a Messenger?" 93
