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 And if We willed, We could surely do away with that which We revealed to you. Then you would not find for yourself concerning it an advocate against Us. 86 Except for Mercy from thy Lord: for his bounty is to thee (indeed) great. 87 Say: "If all mankind and all invisible beings would come together with a view to producing the like of this Qur'an, they could not produce its like even though they were to exert all their strength in aiding one another!" 88 For, indeed, many facets have We given in this Qur'an to every kind of lesson [designed] for [the benefit of] mankind! However, most men are unwilling to accept anything but blasphemy 89 and so they say: "[O Muhammad,] we shall not believe thee till thou cause a spring to gush forth for us from the earth, 90 or, until you own a garden of palms and vines and cause rivers to gush forth with abundant water in them; 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 there be for thee a house of gold or thou mountest to the heaven, and we will by no means believe in thy mounting even until thou causest a book to be sent down to us, which we may read. Say thou: hallowed be my Lord! I am naught but a human being sent as an apostle. 93
