They ask you about "the spirit". Say: "The spirit descends by the command of my Lord, but you have been given only a little knowledge." 85 If We pleased We could take away what We have revealed to you. Then you will not find any one to plead for it with Us, 86 except by the mercy of your Lord. He has certainly bestowed great favors on you. 87 Say: "Surely if men and jinns get together to produce the like of this (Qur'an), they will not be able to produce the like of it, however they might assist one another. 88 Indeed, We have set forth for mankind in this Koran every kind of parable, yet most people refuse all except disbelief. 89 They say: "We shall not believe in thee, until thou cause a spring to gush forth for us from the earth, 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, let chunks of sky fall over us, as you assert (you will); or, bring God and the angels as a surety; 92 Or you have a house of gold or you ascend into the sky. And [even then], we will not believe in your ascension until you bring down to us a book we may read." Say, "Exalted is my Lord! Was I ever but a human messenger?" 93
