(Reporting the speech of Ka`b bin Umra) Allah's Messenger (ﷺ) saw him (i.e. Ka`b) while the lice werefalling on his face. He asked (him), "Have your lice troubled you?" He replied in the affirmative. So,he ordered him to get his head shaved while he was at Al-Hudaibiya. At that time they were notpermitted to finish their Ihram, and were still hoping to enter Mecca. So, Allah revealed the verses ofAl-Fidya. Allah's Messenger (ﷺ) ordered him to feed six poor persons with one Faraq of food or to slaughterone sheep (as a sacrifice) or to fast for three days.
