He has certainly bestowed great favors on you. 87 Say, "If all men and jinn gathered together to produce the like of this Quran, they could not produce one like it, however much they helped one another." 88 We have given examples of every kind to men in this Qur'an in various ways, and even then most men disdain everything but unbelief, 89 And they say, "We will not believe you until you break open for us from the ground a spring. 90 "Or (until) thou have a garden of date trees and vines, and cause rivers to gush forth in their midst, carrying abundant water; 91 or till thou makest heaven to fall, as thou assertest, on us in fragments, or thou bringest God and the angels as a surety, 92 “Or you have a house of gold, or you ascend up into heaven; and even then we shall not believe in your ascent unless you send down a book upon us, which we may read”; say (O dear Prophet Mohammed – peace and blessings be upon him), “Purity is to my Lord – who am I except a human, sent by Allah?” (* These can be done, only when Allah commands.) 93
