Eid al-Adha (Arabic: عيد الأضحى, translit. ʿīd al-aḍḥā, lit. ‘Feast of the Sacrifice’, [ʕiːd ælˈʔɑdˤħæː]), also called the “Sacrifice Feast“, is the second of two Muslim holidays celebrated worldwide each year, and considered the holier of the two. It honors the willingness of Ibrahim (Abraham) to sacrifice his son, as an act of obedience to God‘s command. Before Abraham sacrificed his son, God provided a male goat to sacrifice instead. In commemoration of this, an animal is sacrificed and divided into three parts: one third of the share is given to the poor and needy; another third is given to relatives, friends and neighbors; and the remaining third is retained by the family.
In the Islamic lunar calendar, Eid al-Adha falls on the 10th day of Dhu al-Hijjah. In the international (Gregorian) calendar, the dates vary from year to year drifting approximately 11 days earlier each year.
Like Eid al-Fitr, Eid al-Adha begins with a prayer of two rakats followed by a sermon (khutbah). Eid al-Adha celebrations start after the descent of the Hujjaj, the pilgrims performing the Hajj, from Mount Arafat, a hill east of Mecca. Eid sacrifice may take place until sunset on the 13th day of Dhu al-Hijjah. The days of Eid have been singled out in the Hadith as “days of remembrance” and considered the holiest days in the Islamic Calendar. The takbir (days) of Tashriq are from the Maghrib prayer of the 29th of Dhul-Qadah up to the Maghrib prayer of the 13th of Dhu al-Hijjah (thirteen days and nights).
