And they ask thee regarding the spirit; say thou: the spirit is by the command of my Lord, and ye have not been vouchsafed of knowledge save a little. 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 (Whatever you have received) is nothing but grace from your Lord. Indeed His favour to you is great. 87 Say: If men and jinn should combine together to bring the like of this Quran, they could not bring the like of it, though some of them were aiders of others. 88 And certainly We have explained for men in this Quran every kind of similitude, but most men do not consent to aught but denying. 89 And they said, “We will not accept faith in you, until you cause a spring to gush forth from the earth for us.” 90 Or, until you acquire an orchard of date-palm trees and grapes, and produce rivers flowing through it; 91 or you cause the heavens to fall down on us in pieces, as you have claimed; or you bring God and the angels before us face to face; 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
