Pilgrims performing Stoning of the devil ceremony at 2006 Hajj
Back at Mina, the pilgrims perform symbolic stoning of the devil (Ramy al-Jamarat) by throwing seven stones from sunrise to sunset at only the largest of the three pillars, known as Jamrat al-Aqabah.[15][65][self-published source?] The remaining two pillars (jamarah) are not stoned on this day.[66] These pillars are said to represent Satan.[67] Pilgrims climb ramps to the multi-levelled Jamaraat Bridge, from which they can throw their pebbles at the jamarat. Because of safety reasons, in 2004 the pillars were replaced by long walls, with catch basins below to collect the pebbles.
