Yahya related to me from Malik from Abd al-Karim ibn Malik al-
Jazari from Abd ar-Rahman ibn Abi Layla from Kab ibn Ujra that one
time he was with the Messenger of Allah, may Allah bless him and grant
him peace, in ihram, and he was suffering from lice on his head. The
Messenger of Allah, may Allah bless him and grant him peace, told him
to shave his head, saying, "Fast three days, or feed six poor people,
two mudds for each person, or sacrifice a sheep. If you do any of
those it will be enough for you."
Muwatta Malik Book 20, Hadith 249
On the day of Hudaibiya, the Prophet (ﷺ), the Prophet (ﷺ) made a peace treaty with the Al-Mushrikun on three conditions:
1. The Prophet (ﷺ) would return to them any person from Al-Mushrikun (polytheists, idolaters, pagans).
2. Al-Mushrikun pagans would not return any of the Muslims going to them, and
3. The Prophet (ﷺ) and his companions would come to Makkah the following year and would stay there for three days and would enter with their weapons in cases, e.g., swords, arrows, bows, etc.
Abu Jandal came hopping, his legs being chained, but the Prophet (ﷺ) returned him to Al-Mushrikun.
Sahih al-Bukhari Book 53, Hadith 10
