Random ḥadīth in Nasāʾī's Kubrá
"Ten things are from the Sunnah: Using the Siwak, trimming the mustache, rinsing the mouth, rinsing the nose, letting the beard grow, trimming the nails, plucking the armpit hairs, circumcision, shaving the pubes and washing one's backside." (Using translation from Nasāʾī 5042)
