question #1 Sahih Muslim 1201e, Book 15, Hadith 91 : What are the options available for someone in Ihram who needs to remove vermin from their body?

Do these vermin trouble you? He (Ka’b) said: Yes. The Messenger of Allah (way peace be upon him) said: Shave your head and give some quantity of food enough to feed six needy persons (faraq is equal to three sa’s), or observe fast for three days or offer sacrifice of a sacrificial animal. Ibn Najih (one of the narrators) said:” Or sacrifice a goat.”
