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 willed, We could take away that We have revealed to thee, then thou wouldst find none thereover to guard thee against Us, 86 Except as a mercy from thy Lord verily His grace unto thee is ever great. 87 Say thou: if the mankind and the jinn leagued together that they might produce the like of this Qur'an, they could nor produce the like thereof, though one to the other were a backer. 88 We have mentioned in this Quran all kinds of examples for the human being, but most human beings turn away in disbelief. 89 And say: "We will not believe you until you make a spring of water 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, let chunks of sky fall over us, as you assert (you will); or, bring God and the angels as a surety; 92 Or you should have a house of gold, or you should ascend into heaven, and we will not believe in your ascending until you bring down to us a book which we may read. Say: Glory be to my Lord; am I aught but a mortal apostle? 93
