Men butcher sheep that have been killed for Eid al-Adha - or "Festival of Sacrifice" - an important religious holiday celebrated by Muslims worldwide to commemorate the willingness of Abraham (Ibrahim) to sacrifice his son Ishmael (Isma'il) as an act of obedience to God, before God intervened to provide him with a sheep to sacrifice instead...Those Muslims who can afford to, sacrifice their best domestic animals (usually a cow, but can also be a camel, goat, sheep or ram depending on the region) as a symbol of Abraham's willingness to sacrifice his only son. The sacrificed animals, called U?hiyyah, have to meet certain age and quality standards or else the animal is considered an unacceptable sacrifice. ..The meat from the sacrificed animal is divided into three parts. The family retains one third of the share; another third is given to relatives, friends and neighbors; and the other third is given to the poor and needy. The regular charitable practices of the Muslim community are demonstrated during Eid al-Adha by concerted efforts to see that no impoverished person is left without an opportunity to partake in the sacrificial meal during these days.
