Kaaba

Black Stone

The Black Stone (Arabic: ٱلْحَجَرُ ٱلْأَسْوَد, al-Ḥajaru al-Aswad, 'Black Stone') is a rock set into the eastern corner of the Kaaba, the ancient building in the center of the Grand Mosque in Mecca, Saudi Arabia. It is revered by Muslims as an Islamic relic which, according to Muslim tradition, dates back to the time of Adam and Eve. The stone was venerated at the Kaaba in pre-Islamic pagan times. According to Islamic tradition, it was set intact into the Kaaba's wall by the Islamic prophet Muhammad in 605 CE, five years before his first revelation. Since then, it has been broken into fragments and is now cemented into a silver frame in the side of the Kaaba. Its physical appearance is that of a fragmented dark rock, polished smooth by the hands of pilgrims. Islamic tradition holds that it fell from heaven as a guide for Adam and Eve to build an altar. It has often been described as a meteorite. Muslim pilgrims circle the Kaaba as a part of the tawaf ritual during the hajj and many try to stop to kiss the Black Stone, emulating the kiss that Islamic tradition records that it received from Muhammad. While Muslims revere the Black Stone, they do not worship it. (Wikipedia).
