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 (God)" 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).
