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 please, We should certainly take away that which We have revealed to you, then you would not find for it any protector against Us. 86 Except as a mercy from thy Lord verily His grace unto thee is ever great. 87 Say, "If all men and jinn gathered together to produce the like of this Quran, they could not produce one like it, however much they helped one another." 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 put faith in thee till thou 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 thou cause the skies to fall down upon us in smithereens, as thou hast threatened, or [till] thou bring God and the angels face to face before us, 92 or till thou possessest a house of gold ornament, or till thou goest up into heaven; and we will not believe thy going up till thou bringest down on us a book that we may read. Say: 'Glory be to my Lord. Am I aught but a mortal, a Messenger?' 93
