question #1 Sahih Muslim 1156b, Book 13, Hadith 224 : What was the fasting practice of the Prophet Muhammad (ﷺ) outside of Ramadan?

I said to ‘A’isha (Allah be pleased with her): Did the Messenger of Allah (ﷺ) observe fast during a month? She said, I do not know of any month in which he fasted throughout except Ramadan and (the month) in which he did not fast at all till he ran the course of his life. May peace be upon him.
