question #1 Sahih al-Bukhari 1814, Book 27, Hadith 9 : What are the options provided for expiation if someone is troubled by lice during Hajj or Umrah?

Ka`b bin ‘Ujra said that Allah’s Messenger (ﷺ) said to him (Ka`b), “Perhaps your lice have troubled you?”
Ka`b replied, “Yes! O Allah’s Messenger (ﷺ).” Allah’s Messenger (ﷺ) said, “Have your head shaved and then either
fast three days or feed six poor persons or slaughter one sheep as a sacrifice.”
