It was a bad day to be a sheep.  Eid el Adra celebrates the time when Abraham was tested by God to sacrifice his son.  We will not talk about which of his sons was involved. At the last moment, God told Abraham he had passed the test and provided a ram to sacrifice in place of the son. People around Garut sacrificed rams (and a bull or two) and gave the meat to poor people. My family had four rams and a rather large bull. For dinner we had the meat from both kinds of animals. I think the poor people must have gotten the better cuts.
