It is narrated from Sayyiduna Umar bin al-Khattab (may Allah be pleased with him) that he said: We were in the company of the Prophet (peace and blessings be upon him) when he passed by a man. The people said that this man had been fasting continuously since such-and-such a time and never skipped a day. He (peace and blessings be upon him), expressing his displeasure at this excess, said: "He has neither fasted nor broken his fast." When Sayyiduna Umar (may Allah be pleased with him) saw signs of anger on his (peace and blessings be upon him) blessed face, he said: O Messenger of Allah, what is the ruling if someone fasts two days and breaks the fast one day? He (peace and blessings be upon him) said: "And who has the strength for that?" Then he said: O Messenger of Allah, what do you say about fasting one day and breaking the fast one day? He (peace and blessings be upon him) said: "That is the fasting of my brother Dawud (peace be upon him)." Then he said: O Messenger of Allah, (what of) someone who fasts one day and breaks the fast two days? He (peace and blessings be upon him) said: "And who has the strength for that?" Then he said: O Messenger of Allah, what is the virtue of fasting on Monday? He (peace and blessings be upon him) said: "That is the day on which I was born, and on that same day revelation and prophethood were sent down upon me." He said: O Messenger of Allah, what do you say about the fast of Arafah and Ashura? He (peace and blessings be upon him) said: "One of them (the fast of Ashura) is an expiation for the sins of one year, and the other (the fast of Arafah) wipes out the sins of the previous year and the coming year."
I (Ibn Hajar) say: The preserved (mahfuz) version with this chain is that Abdullah bin Ma'bad narrated it in detail from Sayyiduna Abu Qatadah (may Allah be pleased with him), and Imam Muslim and the compilers of the Sunan recorded it through that route.
