Musnad Abu Ya'la al-Mawsili 150:13

Ishaq narrated to us, Waki’ ibn al-Jarrah narrated to us, Zakariya ibn Abi Za’idah narrated to us, from Mus’ab ibn Shaybah, from Talq ibn Habib, from Ibn al-Zubayr, from ‘Aishah, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "Ten are from the natural disposition (fitrah): trimming the mustache, letting the beard grow, using the siwak, inhaling water into the nose (istinshaq), clipping the nails, washing the knuckles (barajim), plucking the underarm hair, shaving the pubic hair, and cleaning with water." Waki’ said: Meaning cleaning with water (istinja) removes the urine. Zakariya said: Mus’ab said: "And I forgot the tenth, unless it is rinsing the mouth (madmadah)."
