In the Muslim calendar, a holiday begins on the sunset of the previous day. Observing Muslims will celebrate Eid al-Adha on the sunset of the previous day. The festivities begin with a short prayer followed by a sermon. Then people visit family and friends, and exchange greetings and gifts.
The festivities last for two to three days or more depending on the country.
During the festival of Eid al-Adha, Muslims slaughter an animal such as a sheep, camel, or goat. The meat is distributed during the days of the holiday or shortly thereafter. One-third of the meat from the sacrifice of Eid al-Adha is eaten by immediate family and relatives, while another third is given away to friends, and the final third is donated to the poor.
The reason for slaughtering an animal is for Muslims to remind themselves that Allah has given them power over animals and allowed them to eat meat, but only if they pronounce His name at the solemn act of taking life. By saying the name of Allah at the time of slaughter, Muslims are reminded that life is sacred. Muslims always slaughter meat in this manner. The act of slaughtering symbolizes the willingness of Muslims to give up things that are of benefit to them or close to their hearts, in order to follow Allah's commands. It also symbolizes their willingness to give up some of their own abundance, so that they strengthen ties of friendship and help those who are in need.
