Most sacred Muslim shrine, located near the centre of the Great Mosque in Mecca .
All Muslims face toward it in their daily prayers. The cube-shaped structure, made of gray stone and marble, has its corners roughly oriented to the points of the compass; the interior contains only pillars and silver and gold lamps. Pilgrims to Mecca walk around the Ka 02BD; bah seven times and on its eastern side touch the Black Stone of Mecca , which may date from the pre-Islamic religion of the Arabs. Tradition holds that the Ka 02BD; bah was built by Abraham and Ishmael. In 630 Muhammad purged the place of its pagan idols and rededicated it to Islam .
