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 If it were Our Will, We could take away that which We have sent thee by inspiration: then wouldst thou find none to plead thy affair in that matter as against Us,- 86 Except the mercy of your Lord; indeed His munificence upon you (O dear Prophet Mohammed – peace and blessings be upon him) is extremely 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 And We have explained to man, in this Qur'an, every kind of similitude: yet the greater part of men refuse (to receive it) except with ingratitude! 89 And they say, "We will not believe you until you break open for us from the ground a spring. 90 or thou have a garden of date-palms and vines and cause rivers to gush forth in their midst in a sudden rush, 91 or cause the sky to fall into pieces on us - as you believe you can - or bring God and the angels face to face with us, 92 or that there come to be for you a house of gold, or that you ascend to the sky - though we shall not believe in your ascension (to the sky) - until you bring down a book for us that we can read." Say to them, (O Muhammad): "Holy is my Lord! Am I anything else than a human being, who bears a Message (from Allah)?" 93
