They question you about the Spirit. Say, "The Spirit is at my Lord's command, and you have been granted but little knowledge." 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 except by the mercy of your Lord. He has certainly bestowed great favors on you. 87 Say: 'If mankind and jinn combined together to produce the like of this Koran, they would never be able to produce one like it, not even if they were to help one another' 88 We have indeed turned about for men in this Koran every manner of similitude; yet most men refuse all but unbelief. 89 And say: "We will not believe you until you make a spring of water gush forth from the earth for us; 90 or you have a garden of date palms and vines, and cause streams to flow plentifully in the midst of them; 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 you have a house of adornable materials (like silver and pure gold, etc.), or you ascend up into the sky, and even then we will put no faith in your ascension until you bring down for us a Book that we would read." Say (O Muhammad SAW): "Glorified (and Exalted) be my Lord (Allah) above all that evil they (polytheists) associate with Him! Am I anything but a man, sent as a Messenger?" 93
