And they ask thee regarding the spirit; say thou: the spirit is by the command of my Lord, and ye have not been vouchsafed of knowledge save a little. 85 And if We willed We could have taken away the revelations which We have sent to you – you would then not find anyone who could advocate for you before Us for this. 86 (Whatever you have received) is nothing but grace from your Lord. Indeed His favour to you is great. 87 Say: "If the mankind and the jinns were together to produce the like of this Quran, they could not produce the like thereof, even if they helped one another." 88 And indeed We have illustrated all kinds of examples in the Qur’an for mankind – so most men did not accept, except to be ungrateful. 89 And they say: we shall by no means believe in thee until thou causest for us to gush forth from the earth a fountain. 90 Or you should have a garden of palms and grapes in the midst of which you should cause rivers to flow forth, gushing out. 91 or thou cause the skies to fall down upon us in smithereens, as thou hast threatened, or [till] thou bring God and the angels face to face before us, 92 Or there be for thee a house of gold or thou mountest to the heaven, and we will by no means believe in thy mounting even until thou causest a book to be sent down to us, which we may read. Say thou: hallowed be my Lord! I am naught but a human being sent as an apostle. 93
