The Hajj is an annual Islamic pilgrimage to Mecca, the holiest city for Muslims, and a mandatory religious duty for all adult Muslims which must be carried out at least once in their lifetime.
At the first day, the pilgrims are reminded of their duties. The ritual of 'Tawaf' involves walking seven times counterclockwise around the Kaaba and each circuit starts, with the kissing or touching of the Black Stone. The completion of Tawaf is followed by two Rakaat prayers at the Place of Abraham.
