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 Had We willed, We could take away what We have revealed to you, then you would find none to help you in recovering it from Us. 86 except through the special mercy of your Lord. His favours towards you has been great indeed. 87 Say: "Surely, if mankind and jinn were to get together to produce the like of this Qur'an, they will never be able to produce the like of it, howsoever they might help one another." 88 And assuredly We have variously propounded for mankind in this Qur'an every kind of similitude, yet most men have refused everything except infidelity. 89 They say, 'We will not believe thee till thou makest a spring to gush forth from the earth for us, 90 or thou have a garden of date-palms and vines and cause rivers to gush forth in their midst in a sudden rush, 91 Or thou cause the heaven to fall upon us piecemeal, as thou hast pretended, or bring Allah and the angels as a warrant; 92 or, until you possess an ornate house of gold, or ascend into the heavens; and we will not believe in your ascension until you have brought down for us a book which we can read' Say: 'Exaltations to my Lord! Am I anything except a human Messenger' 93
