And they ask you (O Muhammad SAW) concerning the Ruh (the Spirit); Say: "The Ruh (the Spirit): it is one of the things, the knowledge of which is only with my Lord. And of knowledge, you (mankind) have been given only a little." 85 And if We please, We should certainly take away that which We have revealed to you, then you would not find for it any protector against Us. 86 (It is naught) save mercy from thy Lord. Lo! His kindness unto thee was ever great. 87 Say: If men and jinn should combine together to bring the like of this Quran, they could not bring the like of it, though some of them were aiders of others. 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 They have said, "We shall never believe you until you cause a spring to gush forth 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 sky to fall upon us in pieces like you said – or bring Allah and the angels as Witness.” 92 or till thou possessest a house of gold ornament, or till thou goest up into heaven; and we will not believe thy going up till thou bringest down on us a book that we may read. Say: 'Glory be to my Lord. Am I aught but a mortal, a Messenger?' 93
