They ask you about revelation. Say, revelation is by the command of your Lord, and that you have been given but little knowledge. 85 Had We wanted, We could have removed the Spirit through whom We sent you revelation. Then you would not have found anyone to intercede with Us for you 86 [Thou art spared] only by thy Sustainer's grace: behold, His favour towards thee is great indeed! 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 In this Quran, We have set out all kinds of examples for people, yet most of them persist in denying the truth. 89 They say, 'We will not believe thee till thou makest a spring to gush forth from the earth for us, 90 or you have a garden of date palms and vines, and cause streams to flow plentifully in the midst of them; 91 Or, let chunks of sky fall over us, as you assert (you will); or, bring God and the angels as a surety; 92 or thou have a house [made] of gold, or thou ascend to heaven - but nay, we would not [even] believe in thy ascension unless thou bring down to us [from heaven] a writing which we [ourselves] could read! Say thou, [O Prophet:] "Limitless in His glory is my Sustainer! Am I, then, aught but a mortal man, an apostle?" 93
