The Kabah is a sacred structure located in the center of the Masjid al-Haram in Mecca, Saudi Arabia. It is a cube-shaped building made of stone and is covered with a black silk cloth known as the Kiswah. The Kabah is considered the most sacred site in Islam and is the qibla, or direction, that Muslims face during their prayers. Every year, millions of Muslims visit the Kabah to perform the Hajj, a pilgrimage that is one of the Five Pillars of Islam. The structure is believed to have been built by the Prophet Ibrahim (Abraham) and his son Ismail (Ishmael) as a house of worship dedicated to the one God.
