The word 'Eid' appears once in which surah of the Quran?

The word “Eid” appears once in the Quran in Surah Al-Ma'ida.

The occurrence is in Al-Ma'ida, the fifth surah, specifically verse 5:114. In that passage, Jesus asks God to send down a table spread with food from heaven so that the event may become an Eid, understood in this context as a festival, feast, or recurring day of celebration, for the people.

This Quranic occurrence does not describe Eid al-Adha or Eid al-Fitr by name. Those two major Islamic festivals developed within the broader religious tradition and are connected with distinct observances: Eid al-Fitr follows Ramadan, while Eid al-Adha falls during the month of Dhu al-Hijjah and coincides with the Hajj season.

A common mix-up is to assume that the Quranic use of “Eid” directly names one of the two familiar festivals. It does not. The verse uses the Arabic term in the sense of a celebratory feast, while later Muslim practice gives Eid a central place in the names and rituals of both major holidays.
