And they ask you, [O Muhammad], about the soul. Say, "The soul is of the affair of my Lord. And mankind have not been given of knowledge except a little." 85 Had We willed, We could take away what We have revealed to you, then you would find none to help you in recovering it from Us. 86 excepting by some mercy of thy Lord; surly His favour to thee 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 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 thou cause the sky to fall in pieces, as thou sayest (will happen), against us; or thou bring Allah 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
