The event involving a pilgrimage to Mecca, central to the Islamic faith, is called Hajj. This religious duty occurs annually and is one of the Five Pillars of Islam. Every adult Muslim who is physically and financially able must perform this pilgrimage at least once. Hajj includes a series of rituals such as Tawaf, where pilgrims walk around the Kaaba, and the Standing at Arafat, emphasizing spiritual reflection and communal unity among Muslims worldwide.
