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 so willed, We could indeed take away whatever We have revealed unto thee, and in that [state of need] thou wouldst find none to plead in thy behalf before Us. 86 (It is naught) save mercy from thy Lord. Lo! His kindness unto thee was ever great. 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 We have explained things for people in this Qur'an in diverse ways to make them understand the Message, yet most people obstinately persist in unbelief. 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 you have a garden of date-palms and grapes, and you make gushing rivers to flow in it.” 91 “Or you cause the sky to fall upon us in pieces like you said – or bring Allah and the angels as Witness.” 92 or, until you possess an ornate house of gold, or ascend into the heavens; and we will not believe in your ascension until you have brought down for us a book which we can read' Say: 'Exaltations to my Lord! Am I anything except a human Messenger' 93
