Hajj

The Hajj (Arabic: حج‎ Ḥaǧǧ "pilgrimage", also spelled haj) is the largest regularly occurring pilgrimage in the world, and one of the five pillars of Islam, a religious duty that must be carried out by every able-bodied Muslim who can afford to do so at least once in his or her lifetime. The Hajj is a demonstration of the solidarity of the Muslim people, and their submission to God (Allah in the Arabic language).
