  the stoning of the devil ( ,  "stoning of the  [place of pebbles]") is part of the annual islamic hajj pilgrimage to the holy city of mecca in saudi arabia. muslim pilgrims fling pebbles at three walls (formerly pillars), called jamarÄt, 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. on eid al-adha (the 10th day of the month of dhu al-hijjah), pilgrims must strike only one of the large jamrah with seven pebbles. after the stoning is completed on the day of eid, every pilgrim must cut or shave their hair. on each of the following two days, they must hit each of the three walls with seven pebbles, going in order from east to west. thus at least 49 pebbles are needed for the ritual, more if some throws miss. some pilgrims stay at mina for an additional day, in which case they must again stone each wall seven times makes 49 pebbles. the pebbles used in the stoning are traditionally gathered at muzdalifah, a plain southeast of mina, on the night before the first throwing, but can also be collected at mina. == replacement of the pillars == until 2004, the three jamarÄt (singular: jamrah) were tall pillars. after the 2004 hajj, saudi authorities replaced the pillars with  walls for safety; many people were accidentally throwing pebbles at people on the other side. to allow easier access to the jamarÄt, a single-tiered pedestrian bridge called the jamaraat bridge was built around them, allowing pilgrims to throw stones from either ground level or from the bridge. the  are named (starting from the east): * the first  ({{transl|ar|a
