The Prophet (ﷺ) said: When you put on (a garment) and when you perform ablution, you should begin with your right side.
Sunan Abi Dawud Book 34, Hadith 122
← Previous Hadith The Messenger of Allah (ﷺ) liked to begin with the right side as far as possible in all conditions: in his purification, and combing. The narrator Muslim added: "in using tooth-stick," and he did not mention "in all his conditions".

Abu Dawud said: Shu'bah transmitted it from Mu'adh, but did not mention "his tooth-stick."

Sunan Abi Dawud Book 34, Hadith 121 Next Hadith → The Messenger of Allah (ﷺ) mentioned bedding and said: There should be bedding for a man, bedding for his wife, and third for a guest, but a fourth for the devil.
