On Eid al-Adha (the 10th day of the month of Dhu al-Hijjah), pilgrims must strike one of the three jamraat (the Big Jamaraat or Al-Jamrah Al-Aqaba) with seven pebbles. After the stoning is completed on the day of Eid, every pilgrim must cut or shave their hair.[4] 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.
