2425. It was reported from 'Abdullāh bin Ma'bad Az-Zimmānī, from Abū Qatādah who said: "A man came to the Prophet ﷺ and said: 'O Messenger of Allāh! How do you fast?' The Messenger of Allāh ﷺ got angry at what he said. When ‘Umar observed this (his anger), he said: ‘We are satisfied with Allāh as our Lord, Islam as our religion and Muhammad as our Prophet. We seek refuge in Allāh from the anger of Allāh and the anger of His Messenger.’ Umar kept on repeating these words until the anger of Prophet ﷺ receded. He then said: ‘O Messenger of Allāh! What about a person who fasts continuously?’ He said: ‘He is neither fasting, nor breaking fast.’ — in his narration, Musad-dad said: “He has never fasted nor broke his fast, or; he has neither fasted, nor broke fast.” Ghailān (one of the narrators) was in doubt. — “He said: ‘O Messenger of Allāh! What about a person who fasts two days, and does not fast one day?’ He said: ‘Is there anybody who can do that?’ He said: ‘O Messenger of Allāh! What about a person who fasts for a day, and breaks his fast for a day?’ He said: ‘That is the fast of Dāwud.’ He said: ‘O Messenger of Allāh! What about a person who fasts for a day and breaks his fast for two days?’ He said: ‘I wish I could do that.’ Then the Messenger of Allāh ﷺ said: ‘(Fasting) three days from every month, and Ramaḍān to Ramaḍān, this is fasting all the time. And fasting the Day of ‘Arafah; I hope from Allāh that it may expiate for (the sins of) the preceding and the following year. And fasting the Day of ‘Āshūrā’; I hope from Allāh that it may atone for the sins of the preceding year.” (Sahīh)
