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 listed, We could surely take away that which We have revealed unto thee; then thou wilt not find in respect thereof against Us as trustee. 86 But on account of mercy from your Lord-- surely His grace to you is abundant. 87 Say: "If the whole of mankind and Jinns were to gather together to produce the like of this Qur'an, they could not produce the like thereof, even if they backed up each other with help and support. 88 And assuredly We have variously propounded for mankind in this Qur'an every kind of similitude, yet most men have refused everything except infidelity. 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 there be for thee a garden of date-palms and wine, and thou causest in the midst thereof rivers to gush forth. 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 of gold; or thou ascend up into heaven, and even then we will put no faith in thine ascension till thou bring down for us a book that we can read. Say (O Muhammad): My Lord be Glorified! Am I aught save a mortal messenger? 93
