Eid Mubarak (Blessed Eid) is a form of greeting used in connection with the two Islamic Eid festivals, Eid al-Adha and Eid-al Fitr.
Eid al-Adha (The Festival of Sacrifice) is being celebrated in Dubai today. Lasting for three days, it occurs at the conclusion of the annual Hajj, or pilgrimage to Mecca. Muslims all over the world celebrate Eid al-Adha, not simply those undertaking the hajj, which for most Muslims is a once-a-lifetime occurrence.
Eid al-Adha annually falls on the 10th day of the month of Dul Hijja, the last month of the Islamic lunar calendar (or Hijri calender), and is one of the two most important Islamic festivals.
Eid al-Adha commemorates Prophet Abraham’s willingness to obey God when he envisioned that he was to sacrifice his son. Muslims observe this day by slaughtering an animal (usually a sheep) and then offering much of its meat in charity to poor people. The sacrifice symbolizes obedience to Allah and its distribution to others is an expression of generosity, one of the five pillars of Islam.
