context: Kaaba (, IPA: [ælˈkæʕbɐ]; also referred to as Baytu l-Ḥarām, 'holy house' or Baytu l-'Atīq 'ancient house' is used) is a building in Mecca, the holiest place in the Islamic world [1]. A mosque, Masjid al-Haram, has been built around the Kaaba and is the site of the annual pilgrimage of Muslims. Islamic believers perform their prayers all over the world towards the Kaaba.
