On the 10th day of Zul-Hijjah, the last month of the Islamic calendar, Muslims around the world celebrate this feast of commitment, obedience and self sacrifice to Allah. This festival is celebrated throughout the Muslim world as a commemoration of Prophet Abraham's willingness to sacrifice everything for God, including the life of his son Ishmael*. Because God spared Ishmael, substituting a sheep in his stead, Muslims commemorate this occasion by slaughtering an animal and distributing its meat among family, friends and the needy as a special act of charity for the occasion. Because of this, many poor Muslims are able to enjoy the unusual luxury of eating meat during the four days of the festival.
