The Kaaba also referred as Al Kaaba Al Musharrafah (The Holy Kaaba), is a building at the center of Islam's most sacred mosque, Al-Masjid al-Haram, in Mecca, al-Hejaz, Saudi Arabia. It is the most sacred site in Islam. It is considered the "House of Allah" and has a similar role to the Tabernacle and Holy of Holies in Judaism. Wherever they are in the world, Muslims are expected to face the Kaaba when performing salat (prayer). From any point in the world, the direction facing the Kaaba is called the qibla.
