question #1 Sahih Muslim 479b, Book 4, Hadith 237 : What significance does a good vision hold in the context of prophethood and divine messages?

The Messenger of Allah (ﷺ) drew aside the curtain and his head was bandaged on account of illness in which he died. He said: O Allah, have I not delivered (Thy Message)? (He repeated it) three times. Nothing has been left out of the glad tidings of apostlebood, but good vision. which a pious servant (of Allah) sees or someone else is made to see for him. He then narrated like the hadith transmitted by Sufyan.
