And they ask you about the soul. Say: The soul is one of the commands of my Lord, and you are not given aught of knowledge but 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 [We have left it with you] as a mercy from your Lord. Indeed, His favor upon you has ever been great. 87 Say, "If all human beings and jinn were to come together to bring the equivalent of this Quran, they could not do so, even if they all were to help each other. 88 And verily We have displayed for mankind in this Qur'an all kind of similitudes, but most of mankind refuse aught save disbelief. 89 They say, 'We will not believe thee till thou makest a spring to gush forth from the earth for us, 90 "Or you have a garden of date-palms and grapes, and cause rivers to gush forth in their midst abundantly; 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
