Sayyiduna Ammar bin Yasir (may Allah be pleased with them both) narrates that the Noble Prophet (peace and blessings be upon him) said: These acts are from the natural disposition: rinsing the mouth, drawing water into the nose and blowing it out, trimming the moustache, using the tooth-stick (miswak), cutting the nails, washing the joints and tips of the fingers, plucking the hair of the armpits, shaving the pubic hair, performing circumcision, and sprinkling water over the private parts after ablution.
