أهل البيت
This is a simplified family tree of Husayn ibn Ali. People in "italics" are considered by the majority of Shia and Sunni Muslims to be "Ahl al-Bayt" ("People of the House"). Twelver Shia also see the 4th to 12th Imams as Ahl al-Bayt "(Ali is an imam in Mustaali but no number is assigned for this position, and Hasan ibn Ali is not an Imam in Nizari Imamah)".
