Verily! His Grace unto you (O Muhammad SAW) is ever 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 For, indeed, many facets have We given in this Qur'an to every kind of lesson [designed] for [the benefit of] mankind! However, most men are unwilling to accept anything but blasphemy 89 They declare, "We will never believe in you until you cause a spring to flow for us from the earth; 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 thou causest the heaven to fall upon us, as thou assertest, in pieces, or thou bringest God and the angels face to face. 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
