question #1 Sahih Muslim 376d, Book 3, Hadith 157 : What is the significance of maintaining focus and patience during the night prayer?

(The people) stood up for the night prayer when a man spoke forth: I need to say something. The Apostle of Allah (ﷺ) entered into secret conversation with him, till the people dozed off or some of the people (dozed off), and then they said the prayer.
