[Machine] An Arab man came to the Prophet ﷺ and said to him, "O Prophet of Allah, how do you fast or how do you observe fasting?" The Prophet ﷺ remained silent and did not respond to him. When his anger subsided, Umar ibn Al-Khattab asked him and said, "O Prophet of Allah, how do you fast or how do you observe fasting? Have you seen anyone who fasts the entire year?" He replied, "No, he neither fasts nor breaks his fast." Umar said, "O Messenger of Allah, what if someone fasts two days and breaks his fast for one day?" The Prophet ﷺ said, "If someone is able to do that, O Umar, I would have wished to do it." Umar said, "O Messenger of Allah, what if someone fasts one day and breaks his fast for one day?" The Prophet ﷺ said, "That is the fasting of Prophet David (upon him be peace)." Umar then asked, "O Prophet of Allah, what if someone fasts on the day of Arafah?" The Prophet ﷺ said, "It makes up for the previous year and the year after it." Umar asked, "What if someone fasts three days from each month?" The Prophet ﷺ said, "That is the fasting of the entire year." Umar asked, "What if someone fasts on the day of Ashura?" The Prophet ﷺ said, "It makes up for the previous year." Umar said, "O Messenger of Allah, what if someone fasts on Mondays?" The Prophet ﷺ said, "That is the day I was born and the day I received Prophethood."
