Friday prayer, or congregational prayer (Arabic: صَلَاة ٱلْجُمُعَة, romanized: Ṣalāh al-Jumuʿa), is the meeting together of Muslims for communal prayer and a service at midday every Friday.

The meeting service consists of several parts including ritual washing, chants, recitation of scripture and prayer, and sermons or discussions.
