Muslims worldwide celebrate Eid al-Adha, or the Feast of the Sacrifice, by sacrificing sheep, goats, cows or camels. The slaughter commemorates the biblical story of Abraham, who was on the verge of sacrificing his son to obey God's command, when God interceded by substituting a ram in the child's place.
