Eid Al-Adha ("The Feast of the Sacrifice") commemorates Abraham's willingness and obedience to sacrifice his son Ishmael to God (and God's mercy in substituting a lamb for Ishmael). This feast is part of the Haj, and takes place on the tenth of Dhu Al-Hijja of the Islamic calendar. For those on the Hajj and for many others the day begins with the sacrifice of an animal in commemoration of the Angel Gabriel's substitution of a lamb as Abraliam's sacrificial obligation. One-third of the meat is given to the poor, with the remainder shared with neighbors and family members. This holiday is then celebrated in much the same way as Eid Al-Fitr - with good food, gifts for children and general merrymaking.
