Question

anonymous · Answer

The Hajj means "pilgrimage". It is one of the largest pilgrimages in the world, and is the fifth pillar of Islam, a religious duty that must be carried out at least once in their lifetime by every able-bodied Muslim who can afford to do so. The Hajj is a demonstration of the solidarity of the Muslim people, and their submission to God (Allah).

So the answer would be "It is a way to honor the pilgrimage their founder made" ?
