In the Islamic religion, Eid is a very important festival, and stands for love, celebration of life, and utmost and sincere to their God Allah. The two main Eid festivals celebrated during the year by the Muslims are Eid ul Fitr and Eid Ul Adha (also known as Bakri Eid).
On the day of Eid people greet each other with the words Eid Mubarak. While Eid is the name of the festival, Mubarak literally means congratulations. When paraphrased, Eid Mubarak means blessings on the occasion of Eid.
This traditional Muslim greeting is reserved for the festivals of Eid ul-Adha and Eid ul-Fitr. In Arabic the words "Taqabbalallâhu minnâ wa minkum" meaning "may God accept from us and you [our fasts and deeds]", are also used.
