They question you about the spirit. Say: 'The spirit is from the command of my Lord. Except for a little knowledge you have been given nothing' 85 And if We please, We should certainly take away that which We have revealed to you, then you would not find for it any protector against Us. 86 except through the special mercy of your Lord. His favours towards you has been great indeed. 87 Say, "If mankind and the jinn gathered in order to produce the like of this Qur'an, they could not produce the like of it, even if they were to each other assistants." 88 We have indeed turned about for men in this Koran every manner of similitude; yet most men refuse all 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 there be for thee a garden of date-palms and wine, and thou causest in the midst thereof rivers to gush forth. 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, you come to possess a house of gold; or ascend to the skies, though we shall not believe in your having ascended till you bring down a book for us which we could read." Say: "Glory to my Lord. I am only man and a messenger." 93
