Why do Muslims sacrifice an animal on this day?

During the celebration of Eid al-Adha, Muslims commemorate and remember Abraham’s trials, by themselves slaughtering an animal such as a sheep, camel, or goat. This action is very often misunderstood by those outside the faith.

The meat from the sacrifice of Eid al-Adha is mostly given away to others. One-third is eaten by immediate family and relatives, one-third is given away to friends, and one-third is donated to the poor. The act symbolizes our willingness to give up things that are of benefit to us or close to our hearts, in order to follow Allah’s commands. It also symbolizes our willingness to give up some of our own bounties, in order to strengthen ties of friendship and help those who are in need. We recognize that all blessings come from Allah, and we should open our hearts and share with others.

The symbolism is in the attitude – a willingness to make sacrifices in our lives in order to stay on the Straight Path. Each of us makes small sacrifices, giving up things that are fun or important to us. A true Muslim, one who submits his or herself completely to the Lord, is willing to follow Allah’s commands completely and obediently. It is this strength of heart, purity in faith, and willing obedience that our Lord desires from us.

What else do Muslims do to celebrate the holiday?

On the first morning of Eid al-Adha, Muslims around the world attend morning prayers at their local mosques. Prayers are followed by visits with family and friends, and the exchange of greetings and gifts. At some point, members of the family will visit a local farm or otherwise will make arrangements for the slaughter of an animal. The meat is distributed during the days of the holiday or shortly thereafter.
