Lady Aisha (may Allah be pleased with her) narrates that while in the state of i'tikaf, she would pass by the house of a sick person and, while walking, would inquire about their condition. The Messenger of Allah (peace and blessings be upon him), while in the state of i'tikaf, would extend his head out from the mosque towards me, and I would comb his hair. Also, the Messenger of Allah (peace and blessings be upon him) would come home only to perform ablution while in the state of i'tikaf.
