The Messenger of Allah (SAW) said,
“Ten matters are from upright natural disposition: Trimming the moustache, lengthening the beard, using the siwak, rinsing the nose, cutting the nails, washing the joints, plucking the hair under the armpits, shaving pubic hair and cleaning one’s private parts with water (istinja).” The narrator said, “I have forgotten the tenth, but it may have been rinsing the mouth.”
(Sahih Muslim)
