Eid al-Adha, also called the Feast of Sacrifice, is a significant Islamic holiday commemorating Abraham's willingness to sacrifice his son, Ishmael, as an act of obedience to God. This celebration, lasting three to four days, is one of the two main holidays in Islam, the other being Eid al-Fitr. It signifies the conclusion of the hajj (pilgrimage) rites at Minā, Saudi Arabia, near Mecca.
