They ask thee concerning the Spirit (of inspiration). Say: "The Spirit (cometh) by command of my Lord: of knowledge it is only a little that is communicated to you, (O men!)" 85 If it were Our Will, We could take away that which We have sent thee by inspiration: then wouldst thou find none to plead thy affair in that matter as against Us,- 86 [Thou art spared] only by thy Sustainer's grace: behold, His favour towards thee is great indeed! 87 Say: If men and jinn should combine together to bring the like of this Quran, they could not bring the like of it, though some of them were aiders of others. 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 And say: "We will not believe you until you make a spring of water gush forth from the earth for us; 90 or you have a garden of date palms and vines, and cause streams to flow plentifully in the midst of them; 91 or you cause the heavens to fall down on us in pieces, as you have claimed; or you bring God and the angels before us face to face; 92 Or thou have a house of gold; or thou ascend up into heaven, and even then we will put no faith in thine ascension till thou bring down for us a book that we can read. Say (O Muhammad): My Lord be Glorified! Am I aught save a mortal messenger? 93
