They will question thee concerning the Spirit. Say: 'The Spirit is of the bidding of my Lord. You have been given of knowledge nothing except a little.' 85 And if We willed We could surely take away that which We have revealed to you by inspiration (i.e. this Quran). Then you would find no protector for you against Us in that respect. 86 (Whatever you have received) is nothing but grace from your Lord. Indeed His favour to you is great. 87 Say: 'If mankind and jinn combined together to produce the like of this Koran, they would never be able to produce one like it, not even if they were to help 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 They declare, "We will never believe in you until you cause a spring to flow for us from the earth; 90 or till thou possessest a garden of plants and vines, and thou makest rivers to gush forth abundantly all amongst it, 91 Or, let chunks of sky fall over us, as you assert (you will); or, bring God and the angels as a surety; 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
