They ask you about the Spirit. Say, "The Spirit comes by the command of my Lord. You have been given very little knowledge. 85 If We pleased, We would certainly take away that which We have revealed to you, then you would find no guardian for you against Us, 86 except by the mercy of your Lord. He has certainly bestowed great favors on you. 87 Say thou: if the mankind and the jinn leagued together that they might produce the like of this Qur'an, they could nor produce the like thereof, though one to the other were a backer. 88 And indeed We have illustrated all kinds of examples in the Qur’an for mankind – so most men did not accept, except to be ungrateful. 89 And they say: We will by no means believe in you until you cause a fountain to gush forth from the earth for us. 90 or till thou possessest a garden of plants and vines, and thou makest rivers to gush forth abundantly all amongst it, 91 or, until you cause the sky to fall upon us in pieces, as you have claimed, or, as a surety bring Allah with the angels in front; 92 Or you have a house of gold or you ascend into the sky. And [even then], we will not believe in your ascension until you bring down to us a book we may read." Say, "Exalted is my Lord! Was I ever but a human messenger?" 93
