Volume 3, Book 28, Number 42:
Narrated Ka’b bin ‘Umra:
Allah’s Apostle stood beside me at Al-Hudaibiya and the lice were falling from my head in great
number. He asked me, “Have your lice troubled you?” I replied in the affirmative. He ordered me to
get my head shaved. Ka’b added, “This Holy Verse:–‘And if any of you is ill, or has ailment in his
scalp (2.196), etc. was revealed regarding me. “The Prophet then ordered me either to fast three days,
or to feed six poor persons with one Faraq (three Sas) (of dates), or to slaughter a sheep, etc (sacri –
fice) whatever was available.
