The Prophet said, I am very happy to do Siwak

Brushing your teeth will remove germs in your mouth.
Dad said, brushing your teeth is not just about being diligent.
But it must be done with pleasure.
Because if a job is liked, of course it will be easy for us and not forced to do it.
Message of the Prophet Muhammad

That the prophet really enjoyed siwak. (HR. Bukhari)
From Hudzaifah radhiyallahu ‘anhu, he said, “When the Messenger of Allah sallallaahu ‘alaihi wa sallam woke up at night, he rubbed his mouth with siwak.” (Muttafaqun ‘alaih) [HR. Bukhari, no. 889 and Muslim, no. 255]
‘Aisyah radhiyallahu ‘anha said, “We used to prepare miswak and water to purify the Prophet sallallaahu ‘alaihi wa sallam. Allah then woke him up according to His will at night. So he took the siwak, performed ablution, and prayed.” (HR. Muslim) [HR. Muslim, no. 746]
Anas radhiyallahu ‘anhu said, “The Messenger of Allah sallallaahu ‘alaihi wa sallam said, ‘I give you more (recommendations) regarding siwak.” (HR. Bukhari) [HR. Bukhari, no. 888]
Syuraih bin Hani’ said, “I asked ‘Aisyah radhiyallahu ‘anha, ‘With what did the Prophet sallallaahu ‘alaihi wa sallam start with when he entered his house?” ‘Aisyah answered, “With siwak.” (HR. Muslim) [HR. Muslim, no. 253]

Abu Musa Al-Ash’ari radhiyallahu ‘anhu, he said, “I went in to see the Prophet sallallaahu ‘alaihi wa sallam when the tip of the miswak was on his mouth.” (Muttafaqun ‘alaih. This hadith is based on Muslim lafaz) [HR. Bukhari, no. 244 and Muslim, no. 254]
From ‘Aisyah radhiyallahu ‘anha that the Prophet sallallaahu ‘alaihi wa sallam said, “Siwak is a mouth cleanser and (the cause of) the Lord’s pleasure.” (HR. An-Nasai and Ibn Khuzaimah in their authentic book with authentic sanad) [HR. An-Nasai, no. 5 and Ahmad, 6:124. Al-Hafizh Abu Thahir said that this hadith is authentic].
