Or you have a house of ornament [i.e., 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?"
Or you have a house adorned with gold and other things, or you ascend to the sky. And if you do ascend to it, we will never believe you have been sent unless you come down with a book written from Allah in which we can read that you are Allah’s Messenger. Say - O Messenger: My Lord is pure, I am only a human Messenger like all other Messengers. I do not have the ability to bring anything, so how can I bring what you have requested?
