The Messenger of Allah said: “Ten things are part of the Fitrah: Trimming the mustache, trimming the nails, washing the joints, letting the beard grow, using the Siwak, rinsing the nose, plucking the armpit hairs, shaving the pubes, and washing with water (after relieving oneself).” Mus’ab bin Shaibah said: “I have forgotten the tenth, unless it was rinsing the mouth.”
