By Fedwa Wazwaz Eid ul-Adha, or Festival of Sacrifice is one of the major Muslim holidays. It comes right after the fifth pillar of Islam called the Hajj or pilgrimage. The Hajj commemorates the life and trials of Prophet Abraham’s family, upon them peace and blessings. Once in a lifetime, every adult Muslim who has the physical and financial ability is required to make a pilgrimage to the holy city of Makkah, home of the Ka’bah, which Muslims believe was built by Abraham and his son Ishmael.
