Hajj

Three millions of faithful, wearing white robes, converged on the plains of Arafat on Sunday, marking the climax of this year's Hajj.
Hajj is one of the five pillars of Islam and is an obligation on every able-bodied Muslim at least once in their lifetime. The pilgrimage is a spiritual journey that Muslims believe will absolve them of their sins and cleanse their souls, meaning they return home with a clean state.
Many pilgrims have described hajj as a life-changing experience.
