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 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 Except as a mercy from thy Lord verily His grace unto thee is ever great. 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 We have indeed turned about for men in this Koran every manner of similitude; yet most men refuse all but unbelief. 89 And they say: "We shall not believe in you (O Muhammad SAW), until you cause a spring to gush forth from the earth for us; 90 Or, until you acquire an orchard of date-palm trees and grapes, and produce rivers flowing through it; 91 Or you should cause the heaven to come down upon us in pieces as you think, or bring Allah and the angels face to face (with us). 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
