The kaaba is a building at the centre of Islam's most sacred mosque, Al-Masjid al-Haram, in Mecca, Saudi Arabia. It is the most sacred site in Islam. It is considered the "House of Allah (God)". It was built Ibrahim (Abraham) and Ishmael on God's instructions. 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.
