The Black StoneThe Black Stone is an object of reverence, said by some to date back to the time of Adam and Eve, concealed during the great flood and later restored to Abraham for inclusion in the original Ka'bah. The Stone is the eastern cornerstone of the Ka'bah. According to legend, the stone, originally white, was given to Adam on his fall from paradise. It has turned black through absorbing the sins of the thousands of pilgrims who have kissed and touched it.
