And they ask thee regarding the spirit; say thou: the spirit is by the command of my Lord, and ye have not been vouchsafed of knowledge save a little. 85 If it were Our Will, We could take away that which We have sent thee by inspiration: then wouldst thou find none to plead thy affair in that matter as against Us,- 86 except by the mercy of your Lord. He has certainly bestowed great favors on you. 87 Say: "If all mankind and all invisible beings would come together with a view to producing the like of this Qur'an, they could not produce its like even though they were to exert all their strength in aiding one another!" 88 We have explained things for people in this Qur'an in diverse ways to make them understand the Message, yet most people obstinately persist in unbelief. 89 And they said, “We will not accept faith in you, until you cause 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 that there come to be for you a house of gold, or that you ascend to the sky - though we shall not believe in your ascension (to the sky) - until you bring down a book for us that we can read." Say to them, (O Muhammad): "Holy is my Lord! Am I anything else than a human being, who bears a Message (from Allah)?" 93
