What is the last Friday of Ramadan before Eid al-Fitr called?

The last Friday of Ramadan before Eid al-Fitr is called Jumu'atul-Wida.

The Arabic name means “Friday of farewell,” referring to the final Friday prayer, or Jumu'ah, held during Ramadan. In many Muslim communities, worshippers use the occasion for extra prayer, Qur'an recitation, repentance, charity, and reflection as the fasting month draws to a close. It is especially prominent in parts of South Asia and other regions where communal observances have developed around the day.

Jumu'atul-Wida is not the same as Eid al-Fitr, which begins on 1 Shawwal after Ramadan ends. It also should not be confused with Laylat al-Qadr, one of the most sacred nights of Ramadan. Although the day is widely observed culturally and devotionally, the term itself is not prescribed as a distinct festival or special prayer in the Qur'an or hadith; Friday prayer remains the central formal observance.
