question #1 Sahih al-Bukhari 2029, Book 33, Hadith 5 : What activities are permissible for a person in I’tikaf while staying in the mosque?

(the wife of the Prophet) Allah’s Messenger (ﷺ) used to let his head in (the house) while he was in the
mosque and I would comb and oil his hair. When in I`tikaf he used not to enter the house except for a
need.
