A musalla (مصلى) is a space that is not a mosque, mainly used for prayer in Islam. The word comes from صلى (to pray). One use is for the twice-yearly Eid prayers (ʿĪd al-Fiṭr and ʿĪd al-Aḍḥā) and sometimes for funeral prayers as per the Sunnah.

The Prophet's Musalla (PBUH) was an open area located west of Masjid al-Nabi in Medina, where Muhammad (PBUH) performed Eid prayers. Originally, this site served as a resting place for caravan camels and as a market in Medina, known as Manakhah, before it was later called Musalla Square.
