15 October Commemorates the ordeal of Abraham/Ibrahim who was asked to sacrifice his only son to prove his faith to Allah (god). As he was on the point of slaying his son, Allah stopped him and told him that it was but a test of his faith. He was commanded to sacrifice a ram instead. Eid-ul-Azha is celebrated by prayers and by sacrificing goats and sheep. Rituals over this period of The Hajj run over 4 days.
