question #3 Sahih Muslim 632a, Book 5, Hadith 265 : What is the importance of the dawn and afternoon prayers in the context of angelic presence and divine observation?

The Messenger of Allah (ﷺ) said: Angels take turns among you by night and by day, and they all assemble at the dawn and afternoon prayers. Those (of the angels) who spend the night among you, then, ascend, and their Lord asks them, though He is the best informed about them: How did you leave My servants? -they say: We left them while they were praying and we came to them while they were praying.
