But Eid Mubarak is the most popular one.
All over the world, Muslims celebrate two Eids a year- Eid Ul-Fitr and Eid Ul-Adha. Eid Ul-Fitr is celebrated to mark an end of a month long fasting during the month of Ramadan. On the other hand, Eid Ul-Adha, also known as ‘festival of sacrifice’ is a religious festival celebrated to commemorate the willingness of Ibrahim to sacrifice his son Ishmael as an act of obedience to God.
Eid Ul-Fitr is a three day celebration and at time is also known as the ‘Smaller Eid’ as compared to the Eid Ul-Adha that lasts for four days and is called as ‘Greater Eid’. The basis of the celebration of Eid Ul-Adha comes from the Quran. The celebration of both Eid Ul-Fitr and Eid Ul-Adha begins with a short prayer followed by a sermon and then greeting one another saying Eid Mubarak.
