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 Had We willed, We could take away what We have revealed to you, then you would find none to help you in recovering it from Us. 86 except by the mercy of your Lord. He has certainly bestowed great favors on you. 87 Say: "Surely, if mankind and jinn were to get together to produce the like of this Qur'an, they will never be able to produce the like of it, howsoever they might help one another." 88 In this Quran, We have set out all kinds of examples for people, yet most of them persist in denying the truth. 89 And they say, "We will not believe you until you break open for us from the ground a spring. 90 Or [until] you have a garden of palm tress and grapes and make rivers gush forth within them in force [and abundance] 91 or cause the sky to fall on us in pieces as you claimed, or bring Allah and the angels before us, face to face; 92 or that there come to be for you a house of gold, or that you ascend to the sky - though we shall not believe in your ascension (to the sky) - until you bring down a book for us that we can read." Say to them, (O Muhammad): "Holy is my Lord! Am I anything else than a human being, who bears a Message (from Allah)?" 93
