Hair is an adornment for a person, and it protects the head from harm and forms a layer that repels harmful rays from affecting the skin of the head. Lengthening hair - i.e. head hair - was a phenomenon at the time of the Prophet, may God’s prayers and peace be upon him. Indeed, the Messenger of God used to lengthen his hair to his shoulders, and on the authority of Aisha She said: “The Messenger of God, may God’s prayers and peace be upon him, had hair below the bridle and above the bridle.” The bridle was what hung down to the shoulders, and the bridle was what reached the ears.
