They question you about the Spirit. Say, "The Spirit is at my Lord's command, and you have been granted but little knowledge." 85 If We pleased We could take away that which We have revealed to you then you should find none to guard you against Us, 86 (It is naught) save mercy from thy Lord. Lo! His kindness unto thee was ever great. 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 certainly We have explained for men in this Quran every kind of similitude, but most men do not consent to aught but denying. 89 They declare, "We will never believe in you until you cause a spring to flow for us from the earth; 90 “Or you have a garden of date-palms and grapes, and you make gushing rivers to flow in it.” 91 "Or you cause the heaven to fall upon us in pieces, as you have pretended, or you bring Allah and the angels before (us) face to face; 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
