The Prophet (ﷺ) as saying: The inborn characteristics of man are five. Another version says: Five things are of the inborn characteristics of man: circumcision, shaving the pubes, plucking out hair under the armpit, paring the nails and clipping the moustaches.
Sunan Abi Dawud Book 35, Hadith 40
← Previous Hadith Al-Hajjaj ibn Hassan said: We entered upon Anas ibn Malik. My sister al-Mughirah said: You were a boy in those days and you had two locks of hair. He (Anas) rubbed your head and invoked blessing on you. He said: Shave them (i.e. the locks) or clip them, for this is the fashion of the Jews.
