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 surely do away with that which We revealed to you. Then you would not find for yourself concerning it an advocate against Us. 86 (Whatever you have received) is nothing but grace from your Lord. Indeed His favour to you is great. 87 Say: "Surely if men and jinns get together to produce the like of this (Qur'an), they will not be able to produce the like of it, however they might assist one another. 88 And indeed We have fully explained to mankind, in this Quran, every kind of similitude, but most mankind refuse (the truth and accept nothing) but disbelief. 89 They say, 'We will not believe thee till thou makest a spring to 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 you cause the sky to fall upon us in pieces like you said – or bring Allah and the angels as Witness.” 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
