Sayyiduna Ka'b bin Ujrah (may Allah be pleased with him) narrates: The Noble Prophet (peace and blessings of Allah be upon him) saw him while lice were falling onto his face; this was at the place of Hudaybiyyah. The Noble Prophet (peace and blessings of Allah be upon him) asked him: "Are the lice troubling you?" He replied: "Yes!" So the Noble Prophet (peace and blessings of Allah be upon him) ordered him to shave his head, even though he was at the place of Hudaybiyyah at that time, and the Prophet had not yet announced to the people that they would end their ihram there, because the people wanted to enter Makkah. Then Allah revealed the command of fidyah, so the Noble Prophet (peace and blessings of Allah be upon him) instructed him to distribute one sa' among six poor people, or to sacrifice a goat, or to fast for three days.
