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 And if We willed We could have taken away the revelations which We have sent to you - you would then not find anyone who could advocate for you before Us for this. 86 except for Mercy from your Lord; for His favor to you is great indeed. 87 Proclaim, "If all mankind and jinns agree to bring an equivalent to the Qur'an, they will not be able to bring its equal - even if they were to help each other." 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 say, "We will not believe you until you break open for us from the ground a spring. 90 "Or (until) thou have a garden of date trees and vines, and cause rivers to gush forth in their midst, carrying abundant water; 91 Or thou cause the heaven to fall upon us piecemeal, as thou hast pretended, or bring Allah and the angels as a warrant; 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
