Say: The soul is one of the commands of my Lord, and you are not given aught of knowledge but a little. 85 And if We willed We could withdraw that which We have revealed unto thee, then wouldst thou find no guardian for thee against Us in respect thereof. 86 But on account of mercy from your Lord-- surely His grace to you is abundant. 87 Say: 'If men and jinn banded together to produce the like of this Koran, they would never produce its like, not though they backed 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 said: "We shall not accept your Message until you cause a spring to gush forth for us from the earth; 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 thou cause the sky to fall in pieces, as thou sayest (will happen), against us; or thou 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
