Black Stone
The Black Stone (called Al-Hajarul Aswad in Arabic) is one of the most sacred holy relics in Islam. It is generally believed to be a fragment of a meteorite, roughly 50 cm in diameter. It is the foundation of the Kaaba, the most sacred mosque in Islam. It is the cornerstone of one of the four corners of the religious construction, though it can be recognized instantly because it is surrounded by a silver band. The Stone is actually broken into several pieces, and the band holds them together. Silver nails are used to fasten the silver band to the Stone.Muslims believe that this stone fell from the sky during the time of Adam, and that it has the power to cleanse worshippers of their sins by absorbing them into itself. The Black Stone is believed to have originally been colored white, but it turned black because of the sins it has absorbed over the years.
As part of the Kaaba, the Black Stone resides in the city of Mecca. Muslims who have come to Mecca for the hajj try to kiss or caress the stone and Kaaba, or at least point to it, when they arrive during the pilgrimage. Islam dictates that pilgrims circle the Kaaba seven times.
