Then you would not find for yourself concerning it an advocate against Us. 86 Except the mercy of your Lord; indeed His munificence upon you (O dear Prophet Mohammed – peace and blessings be upon him) is extremely great. 87 Say: "Surely if men and jinns get together to produce the like of this (Qur'an), they will not be able to produce the like of it, however they might assist one another. 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 They say: "We shall not believe in thee, until thou cause a spring to gush forth for us from the earth, 90 Or thou have a garden of date-palms and grapes, and cause rivers to gush forth therein abundantly; 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 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
