They will question thee concerning the Spirit. Say: 'The Spirit is of the bidding of my Lord. You have been given of knowledge nothing except a little.' 85 If We pleased We could take away what We have revealed to you. Then you will not find any one to plead for it with Us, 86 excepting by some mercy of thy Lord; surly His favour to thee 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 We have certainly diversified for the people in this Qur'an from every [kind] of example, but most of the people refused [anything] except disbelief. 89 They say: 'We will not believe in you until you make a spring gush 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, 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
