The Al-Hannanah Mosque, also known as the Mosque of the Head, is a Shi'ite mosque, located in Najaf, in the Najaf Governorate of Iraq. The term "Mosque of the Head" is because the head of Husayn ibn Ali was kept in its middle, while being taken to his opponent Ubayd Allah ibn Ziyad, according to a hadith (narration) attributed to his descendant, Ja'far al-Sadiq.
