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 If We pleased, We would certainly take away that which We have revealed to you, then you would find no guardian for you against Us, 86 except for Mercy from your Lord; for His favor to you is great indeed. 87 Say, "If all men and jinn gathered together to produce the like of this Quran, they could not produce one like it, however much they helped 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 (until) thou have a garden of date trees and vines, and cause rivers to gush forth in their midst, carrying abundant water; 91 Or you make the heaven fall upon us in fragments as you have claimed or you bring Allah and the angels before [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
