Narrated to me Abu al-Tahir and Harmalah ibn Yahya, both saying: Ibn Wahb informed us, Yunus informed me, from Ibn Shihab, from Sa'id ibn al-Musayyab, from Abu Hurayrah, from the Messenger of Allah (peace be upon him) that he said: "Five things are part of the fitrah: circumcision, shaving the pubic hair, trimming the mustache, clipping the nails, and plucking the armpit hairs."
