Afghani Muslim pilgrim casts stones at a pillar, symbolizing the stoning of Satan, in a ritual called „Jamarat,” a rite of the annual hajj, or pilgrimage, in Mina near the Saudi holy city of Mecca, Saudi Arabia, Tuesday, Oct. 15, 2013. The hajj, a central pillar of Islam and one that able-bodied Muslims must make once in their lives, is a four-day spiritual cleansing based on centuries of interpretation of the traditions of Prophet Muhammad.
