SHAFAQNA (Shia International News Association) - The Kaaba is a cuboid-shaped building in Mecca, Saudi Arabia, and is the most sacred site in Islam. The Qur'an states that the Kaaba was constructed by Prophet Abraham (P), and his son Prophet Ismail (P), after the latter had settled in Arabia. The building has a mosque built around it, the Masjid al-Haram. All Muslims around the world face the Kaaba during prayers, no matter where they are. This is called facing the Qiblah.
One of the ten branched (Furoo-e-deen) of Islam requires every Muslim to perform the Hajj (pilgrimage) at least once in his or her lifetime if able to do so. Multiple parts of the Hajj require pilgrims to walk seven times around the Kaaba in a counter-clockwise direction. This circumambulation, the Tawaf, is also performed by pilgrims during the Umrah (lesser pilgrimage).
