They ask you about revelation. Say, revelation is by the command of your Lord, and that you have been given 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 (It is naught) save mercy from thy Lord. Lo! His kindness unto thee was ever 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 For, indeed, many facets have We given in this Qur'an to every kind of lesson [designed] for [the benefit of] mankind! However, most men are unwilling to accept anything but blasphemy 89 And they say, "We will not believe you until you break open for us from the ground a spring. 90 Or, until you acquire an orchard of date-palm trees and grapes, and produce rivers flowing through it; 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 till thou possessest a house of gold ornament, or till thou goest up into heaven; and we will not believe thy going up till thou bringest down on us a book that we may read. Say: 'Glory be to my Lord. Am I aught but a mortal, a Messenger?' 93
