They are asking thee concerning the Spirit. Say: The Spirit is by command of my Lord, and of knowledge ye have been vouchsafed but little. 85 And if We listed, We could surely take away that which We have revealed unto thee; then thou wilt not find in respect thereof against Us as trustee. 86 Except as a mercy from thy Lord verily His grace unto thee is ever 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 mentioned in this Quran all kinds of examples for the human being, but most human beings turn away in disbelief. 89 They said: "We shall not accept your Message until you cause a spring to gush forth for us from the earth; 90 Or [until] you have a garden of palm tress and grapes and make rivers gush forth within them in force [and abundance] 91 or cause the sky to fall into pieces on us - as you believe you can - or bring God and the angels face to face with us, 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
