Abdur-Rahman bin Abu Laila narrated from Ka'b bin Ujrah that:
The Prophet passed by him while he was at Al-Hudaibiyah, before entering Makkah, and he was a Muhrim. He had lit a fire under a cooking pot and lice were falling all over his face. So he (the Prophet) said: Have these lice of yours troubled you? He said: Yes. He said: Shave and feed six of the poor with a Faraq and a Faraq is three Sa - or fast three days, or slaughter a sacrifice. Ibn Abi Najih (one of the narrators) said: Or slaughter a sheep.
