After the prayer on Eid al-Adha, Muslims who are able offer a udhiyah (sacrifice) of an animal, such as a sheep, goat, cow or camel. The Prophet ﷺ said, "The first thing we begin with on this day of ours is to pray, then to return and sacrifice" (Sahih al-Bukhari 5545). He sacrificed two horned rams with his own hand, saying the name of Allah and "Allahu akbar" (Sahih al-Bukhari 5558). The animal must meet the conditions of age and health, so it must be free of clear defects such as obvious blindness, illness, lameness or extreme thinness (Sunan Abi Dawud 2802), and it is slaughtered in the way Islam teaches.
Scholars differ on its status. The Hanafi school says it is required (wajib) for those who have the means, while the Maliki, Shafi'i and Hanbali schools say it is a confirmed sunnah.
Quran 22:36 tells us to eat from it and to feed the needy, and the Prophet ﷺ said, "Eat, feed and store" (Sahih al-Bukhari 5569). As commonly taught, the meat is shared in three parts: one for the family, one for relatives, friends and neighbours, and one for the poor. This is a recommendation and not a fixed rule, and some scholars allow other proportions.
Fasting is forbidden on the day of Eid al-Fitr and on the day of Eid al-Adha (Sahih al-Bukhari 1990; Sahih Muslim 1137). These are days of eating and enjoying the gifts of Allah.
