question #3 Sahih Muslim 738e, Book 6, Hadith 156 : How does the Prophet Muhammad (ﷺ) structure his prayers during the night and dawn?

It is reported on the authority of ‘A’isha that the prayer of Allah’s Messenger (ﷺ) in the night consisted of ten rak’ahs. He observed a Witr and two rak’ahs (of Sunan) of the dawn prayer, and thus the total comes to thirteen rak’ahs.
