Say: The soul is one of the commands of my Lord, and you are not given aught of knowledge but a little. 85 And if We willed, We could surely do away with that which We revealed to you. Then you would not find for yourself concerning it an advocate against Us. 86 But on account of mercy from your Lord-- surely His grace to you is abundant. 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 verily We have displayed for mankind in this Qur'an all kind of similitudes, but most of mankind refuse aught save disbelief. 89 They say: "We shall not believe in thee, until thou cause a spring to gush forth for us from the earth, 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 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 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
