Eid-Ul-Adha is a four-day holiday and celebration. It commences on the 10th day of Thul Hijjah and is celebrated in a manner similar to Eid-Ul-Fitr. It starts with a special holiday prayer, performed in congregation in the Masjid (Mosque) or other suitable place. It is a time of celebration, of visiting family and friends and of thanking almighty Allah. It also marks the completion of the of the hajj (pilgrimage) rites undertaken by many people every year at Mina, Saudi Arabia. Eid-Ul- Adha is an important day in the Islamic calendar and is observed by Muslims all over the world to commemorate the faith of Ibrahim (Abraham).
The festival commemorates God's gift of a ram in place of Isma'il (Ishmael, Ibrahims son), whom God had commanded Ibrahim (Abraham) to sacrifice. While the Devil had tried to persuade Ibrahim to disobey God by not sacrificing his son, Ibrahim on his part remained steadfast and loyal to the word of God. He prepared to submit to Allah's will. When he was all prepared to do it, Allah revealed to him that his "sacrifice" had already been fulfilled. The Lord provided a ram for the sacrifice, and preserved his two faithful subjects.
Ibrahim had shown that his love for his Lord superceded all others that he would lay down his own life or the lives of those dear to him in order to submit to God. Eid al-Adha is a celebration of this supreme example of submission to God, which is the cornerstone of the Islamic faith (islam means "submission").
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. Normally, they keep one third of the meat from the sacrifice, distribute one third to the needy and share one third with their neighbors.
Eid al-Adha is called Id-ul-Adha in Arabic and Bakr-Id in the Indian subcontinent, because of the tradition of sacrificing a goat or "bakr" in Urdu. The word "id" derived from the Arabic "iwd" means "festival" and "zuha" comes from "uzhaiyya" which translates to "sacrifice".
On the first morning of Eid al-Adha, Muslims all round the world attend early prayers at the Masjid. Prayers are followed by visits with family and friends, and the exchange of greetings and gifts. They then make animal sacrifice, a potion of which they also give away to the needy and the family and friends get together to have a nice sumptuous meal.
