question #2 Sahih Muslim 749d, Book 6, Hadith 180 : What is the significance of the Witr prayer in the context of night prayers?

A person asked the Messenger of Allah (ﷺ) as I stood between him (the Holy Prophet) and the inquirer and he said: Messenger of Allah, how is the night prayer? He (the Holy Prophet) said: It consists of pairs of rak’ahs, but if you apprehend morning, you should pray one rak’ah and make the end of your prayer as Witr. Then a person asked him (the Holy Prophet) at the end of the year and I was at that place near the Messenger of Allah (ﷺ) ; but I do not know whether he was the same person or another person, but he (the Holy Prophet) gave him the same reply.
