They will question thee concerning the Spirit. Say: 'The Spirit is of the bidding of my Lord. You have been given of knowledge nothing except a little.' 85 And if We willed We could surely take away that which We have revealed to you by inspiration (i.e. this Quran). Then you would find no protector for you against Us in that respect. 86 except by the mercy of your Lord. He has certainly bestowed great favors on you. 87 Say: "If the whole of mankind and Jinns were to gather together to produce the like of this Qur'an, they could not produce the like thereof, even if they backed up each other with help and support. 88 We have indeed turned about for men in this Koran every manner of similitude; yet most men refuse all but unbelief. 89 They say: 'We will not believe in you until you make a spring gush from the earth for us, 90 Or [until] you have a garden of palm tress and grapes and make rivers gush forth within them in force [and abundance] 91 or till thou makest heaven to fall, as thou assertest, on us in fragments, or thou bringest God and the angels as a surety, 92 or (show us) that you have a well adorned house of your own, or climb into the sky. We shall never believe that you have climbed into the sky until you bring us a book that we can read." Say, "All glory belongs to my Lord. Am I more than a mortal Messenger?" 93
