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 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 as a mercy from thy Lord verily His grace unto thee is ever great. 87 Proclaim, “If all mankind and jinns agree to bring an equivalent to the Qur’an, they will not be able to bring its equal – even if they were to help each other.” 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 they say: we shall by no means believe in thee until thou causest for us to gush forth from the earth a fountain. 90 or, until you own a garden of palms and vines and cause rivers to gush forth with abundant water in them; 91 or, until you cause the sky to fall upon us in pieces, as you have claimed, or, as a surety bring Allah with the angels in front; 92 "Or thou have a house adorned with gold, or thou mount a ladder right into the skies. No, we shall not even believe in thy mounting until thou send down to us a book that we could read." Say: "Glory to my Lord! Am I aught but a man,- a messenger?" 93
