Ahl al-Bayt (أهل البيت‎, Persian: اهلِ بیت‎), also Āl al-Bayt or Ahlul Bayt, is a phrase meaning, literally, "People of the House" or "Family of the House". Within the Islamic tradition, the term refers to the family of the Islamic prophet Muhammad.In Shia Islam the Ahl al-Bayt are central to Islam and interpreters of the Quran and Sunnah. Shias believe they are successors of Muhammad and consist of Muhammad, Fatimah, Ali, Hasan, and Husayn (known collectively as the Ahl al-Kisa, "people of the mantle") and the rest of the Imams from The Fourteen Infallibles.
