the second of two great Muslim festivals, the other being Īd al-Fiṭrʿ. ʿĪd al-Aḍḥā marks the culmination of the hajj (pilgrimage) rites at Minā, Saudi Arabia, near Mecca, but is celebrated by Muslims throughout the world. As with ʿĪd al-Fiṭr, it is distinguished by the performance of communal prayer (ṣalāt (salat)) at daybreak on its first day. It begins on the 10th of Dhu'l-Hijja, the last month of the Islamic calendar, and continues for an additional three days (though the Muslim use of a lunar calendar means that it may occur during any season of the year). During the festival, families that can afford to sacrifice a ritually acceptable animal (sheep, goat, camel, or cow) and then divide the flesh equally among themselves, the poor, and friends and neighbours. ʿĪd al-Aḍḥā is also a time for visiting with friends and family and for exchanging gifts. This festival commemorates the ransom with a ram of the biblical patriarch Ibrāhīm's (Abraham's) son Ismāʿīl (Ishmael)—rather than Isaac, in Judeo-Christian tradition. See also mawlid; Āshūrāʾʿ.
