Narrated Abu Burdah: On the authority of his father ( Abu Musa al-Ashari), reported (according to the version of Musaddad): We came to the Messenger of Allah ﷺ to provide us with a mount, and found him using the tooth-stick, its one end being at his tongue (i. e. he wsa rinsing his mouth). According to the version of Sulaiman it goes: I entered upon the Prophet ﷺ who was using the tooth-stick, and had it placed at one side of his tongue, producing a gurgling sound. Abu Dawud said: Musaddad said that the tradition was a lengthy but he shortened it.

Mutarrif said: I and Imran bin Husain offered prayer behind ‘All bin AbI Talib (may Allah be pleased with him). When he prostrated, he uttered the takbir (Allah is most great) and when he bowed, he uttered the takbir and when he stood up at the end of two rak’ahs, he uttered the takbir. When we finished our prayer, Imran caught hold of my hand, and said: He has led us in prayer just now like the prayer offered by Muhammed (may peace by upon him).

Narrated Abu Qatadah: A man came to the Prophet ﷺ and said: How do you fast, Messenger of Allah? The Messenger of Allah ﷺ became angry at what he said. When Umar observed this (his anger), he said: We are satisfied with Allah as Lord, with Islam as religion, and with Muhammad as Prophet. We seek refuge in Allah from the anger of Allah, and from the anger of His Messenger. Umar continued to repeat these words till his anger cooled down. He then asked: Messenger of Allah, what is the position of one who observes a perpetual fast? He replied: May he not fast or break his fast. Musaddad said in his version: He has neither fasted nor broken his fast. The narrator, Ghaylan, doubted the actual wordings. He asked: What is the position of one who fasts two days and does not fast one day? He said: Is anyone able to do that? He asked: What is the position of one who fasts every second day (i. e. fasts one day and does not fasts the next day)? He (the Prophet) said: This is the fast that David observed. He asked: Messenger of Allah, what is the position of one who fasts one day and breaks it for two days? He replied: I wish I were given the power to observe that. Then the Messenger of Allah ﷺ said: The observance of three days' fast every month and of one Ramadan to the other (i. e. the fast of Ramadan every year) is (equivalent to) a perpetual fast. I seek from Allah that fasting on the day of Arafah may atone for the sins of the preceding and the coming year, and I seek from Allah that fasting on the day of Ashura' may atone for the sins of the preceding year.

The tradition mentioned above has also been transmitted by Abu Qatadah through a different chain of narrators. This version add: He said: Messenger of Allah, tell me about keeping fast on Monday and Thursday. He said: On it I was born, and on it the Quran was first revealed to me.

Narrated Abu Burdah: On the authority of his father that the Prophet ﷺ said: I swear by Allah that if Allah wills I shall swear on an oath and then consider something else to be better than it without making atonement for my oath and doing the thing that is better. Or he said (according to another version): But doing the thing that is better and making atonement for my oath.
