Narrated Abu Burdah (RA) : 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.
