You have been given very little knowledge. 85 If We pleased We could take away that which We have revealed to you then you should find none to guard you against Us, 86 But on account of mercy from your Lord-- surely His grace to you is abundant. 87 Say, "If all human beings and jinn were to come together to bring the equivalent of this Quran, they could not do so, even if they all were to help each other. 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 said, “We will not accept faith in you, until you cause a spring 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 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 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
