Eid al-Adha is celebrated on the tenth day of Zil Hijjah, the twelfth and the last month of the Islamic calendar. It is a very joyous day; it is a feast of self-sacrifice, commitment and obedience to Allah (swt). It commemorates the great act of obedience to Allah (swt) by the Prophet Ibrahim (asws) in showing his willingness to sacrifice his son Ismael (asws). Allah (swt) accepted his sacrifice and replaced Prophet Ismael (asws) with a lamb. Although Hajj has no relation with the Eid al-Adha, the five days long rituals of Hajj are also done during this month culminating on 9th of ZilHijjah. Many rituals of Hajj are symbolic enactments of the struggle of the family of Ibrahim (asws), especially his second wife, Hajirah (ra) and her son, Prophet Ismael (asws). Those who have enough wealth to pay Zakah must offer the sacrifice for Allah (swt). It is the tradition of Prophet Ibrahim (asws) and a strongly recommended Sunnah. A lamb, sheep, goat, cow, buffalo, or camel can be offered as the sacrifice. There are seven shares in a cow, buffalo and camel. The sacrifice should be accomplished by slaughtering the animal after Salah-al-Eid.
