[Machine] A man asked the Messenger of Allah ﷺ, "O Messenger of Allah, what do you think about a man who fasts on the day of Ashura?" He said, "That is the fasting of a Sunnah." The man asked, "And what about a man who fasts on the day of Arafah?" He said, "It expiates the sins of the previous year and the coming year."
