The Black Stone (called الحجر الأسود al-Hajr e Aswad in Arabic) is a Muslim relic, which according to Islamic tradition dates back to the time of Adam and Eve. Historical research claims that the Black Stone marked the Kaaba as a place of worship during pre-Islamic pagan times. It is the eastern cornerstone of the Kaaba, the ancient stone building towards which Muslims pray, in the center of the Grand Mosque in Mecca, Saudi Arabia. The Stone is a dark rock, polished smooth by the hands of millions of pilgrims, that has been broken into a number of fragments cemented into a silver frame in the side of the Kaaba. Although it has often been described as a meteorite, this hypothesis is still under consideration.
Muslim pilgrims circle the Kaaba as part of the Tawaf ritual of the Hajj. Many of them try, if possible, to stop and kiss the Black Stone, emulating the kiss that Islamic tradition records that it received from the Prophet Muhammad. If they cannot reach it, they point to it on each of their seven circuits around the Kaaba.
