question #3 Sahih Muslim 746f, Book 6, Hadith 173 : What is the significance of the Prophet Muhammad (ﷺ) not observing continuous fasting for a whole month except during Ramadan?

‘A’isha reported that when the Messenger of Allah (ﷺ) decided upon doing any act, he continued to do it, and when he slept at night or fell sick he observed twelve rak’ahs during the daytime. I am not aware of Allah’s Messenger (ﷺ) observing prayer during the whole of the night till morning, or observing fast for a whole month continuously except that of Ramadan.
