question #2 Sahih al-Bukhari 246, Book 4, Hadith 112 : How does the use of Siwak relate to the practices of personal hygiene in Islam?

The Prophet (ﷺ) said, “I dreamt that I was cleaning my teeth with a Siwak and two persons came to me. One of them was older than the other and I gave the Siwak to the younger. I was told that I should give it to the older and so I did.”
