It is narrated from Hazrat Aisha (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) said: Ten things are part of natural disposition (fitrah): trimming the moustache, letting the beard grow, using the miswak, cleaning the nose with water, cutting the nails, washing the joints of the fingers, plucking the hair from the armpits, shaving the pubic hair, and cleaning oneself with water after relieving oneself. The narrator, Hazrat Mus'ab, says: I forgot the tenth characteristic, and most likely it is rinsing the mouth.

Hazrat Abu Huraira narrates that the Noble Prophet (peace and blessings be upon him) said: Five things are part of natural disposition: circumcision, shaving the pubic hair, trimming the nails, plucking the armpit hair, and shortening the moustache.

Hazrat Ammar bin Yasir narrates that the Messenger of Allah, peace and blessings be upon him, said: The characteristics of nature are these: rinsing the mouth, cleaning the nose, using the miswak, trimming the moustache, plucking the armpit hair, washing the joints of the fingers, trimming the nails, cleaning oneself with water after relieving oneself, and circumcision.

Hazrat Mujahid says that six things are part of the natural disposition (fitrah) of Ibrahim: trimming the moustache, using the miswak, parting the hair, cutting the nails, performing istinja (cleaning oneself after relieving oneself), and shaving the hair below the navel. Three are related to the head and three are related to the rest of the body.
