You have been given of knowledge nothing except a little.' 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 excepting by some mercy of thy Lord; surly His favour to thee is great. 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 They say, 'We will not believe thee till thou makest a spring to gush forth from the earth for us, 90 or you (show) us that you have your own garden of palm trees and vines with flowing streams therein, 91 "Or you cause the heaven to fall upon us in pieces, as you have pretended, or you bring Allah and the angels before (us) face to face; 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
