Hajj

Hajj, or Hadj, pilgrimage to the Muslim world's holiest city, Mecca, in what is now Saudi Arabia. The goal of a hajj is the mosque whose court encloses the Kaaba, a cube-shaped building containing the sacred Black Stone. Muslims are required to make the pilgrimage to Mecca at least once in their lifetime, if at all possible.
