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.

The Noble Prophet (peace and blessings of Allah be upon him) said: "Shave your head." (The narrator states) Then this verse was revealed: "So whoever among you is ill or has an ailment of the head, then (he should offer) a ransom of fasting or charity or sacrifice."
