They question you about the spirit. Say: 'The spirit is from the command of my Lord. Except for a little knowledge you have been given nothing' 85 If We pleased, We would certainly take away that which We have revealed to you, then you would find no guardian for you against Us, 86 But on account of mercy from your Lord-- surely His grace to you is abundant. 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 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 there be for thee a garden of date-palms and wine, and thou causest in the midst thereof rivers to gush forth. 91 Or, let chunks of sky fall over us, as you assert (you will); or, bring God and the angels as a surety; 92 Or you should have a house of gold, or you should ascend into heaven, and we will not believe in your ascending until you bring down to us a book which we may read. Say: Glory be to my Lord; am I aught but a mortal apostle? 93
