Bani Haritsah Mosque (), or Masjid Al-Mustarah, is a mosque located in Medina, Saudi Arabia. It is located at Sayyid asy-Syuhada' street. The naming comes from an account of the Islamic prophet Muhammad taking a rest in this place once, during the way home returning from the Battle of Uhud. The word "Mustarah" means the place for resting.
