Stoning of the Devil or stoning of the jamarat (Arabic: ramy al-jamarāt) is part of the annual Islamic Hajj pilgrimage to the holy city of Mecca in Saudi Arabia. Muslim pilgrims fling pebbles at three walls called jamarat in the city of Mina just east of Mecca. It is one of a series of ritual acts that must be performed in the Hajj, and routinely attracts vast crowds of over a million pilgrims.
Traditionally the three jamarat (singular: jamrah) were tall pillars. However, after the 2004 Hajj, Saudi authorities replaced the pillars with 26-meter-(85 ft) long walls  to ease performance of the ritual and make it less dangerous to pilgrims. The jamarat are named (starting from the east) the first or smallest jamrah (Arabic: al-jamrah al-ula or al-jamrah as-sughra), the middle jamrah (al-jamrah al-wusta), and the largest jamrah or jamrah of Aqaba (al-jamrah al-kubra or jamrat al-`Aqabah).
