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 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 (Whatever you have received) is nothing but grace from your Lord. Indeed His favour to you is great. 87 Say, "If mankind and the jinn gathered in order to produce the like of this Qur'an, they could not produce the like of it, even if they were to each other assistants." 88 We have indeed turned about for men in this Koran every manner of similitude; yet most men refuse all but unbelief. 89 And they say: We will not put faith in thee till thou cause a spring to gush forth from the earth for us; 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, 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 gold, or you ascend up into heaven; and even then we shall not believe in your ascent unless you send down a book upon us, which we may read”; say (O dear Prophet Mohammed – peace and blessings be upon him), “Purity is to my Lord – who am I except a human, sent by Allah?” (* These can be done, only when Allah commands.) 93
