On the authority of Aisha, she said: The Messenger of God said: “Ten things are from the natural instinct: cutting the moustache, letting the beard grow, Miswāk (brushing the teeth with an Arāk twig), Istinshāq (sniffing with water to clean the nose), clipping the nails, washing the knuckles (skin crevices), plucking the armpits, shaving the pubic hair, and reducing the water” means cleaning oneself with water after toilette. Zakariyā [one of the hadith's narrators] said: Mus‘ab ibn Shaybah [one of the hadith's narrators] said: I forgot the tenth, unless it is Maḍmaḍah (shaking water and rinsing the mouth).
