Jumu'ah (also rendered jum'ah; Arabic: صلاة الجمعة‎ ṣalāt al-jumuʿah, "Friday prayer") is a congregational prayer (salah) that Muslims hold every Friday, just after noon in the place of dhuhr. Muslims pray ordinarily five times each day according to the sun's sky path regardless of clock time. . It is mentioned in the Qur'an as:

The jumuʿah prayer is half the ẓuhr (dhuhr) prayer, for convenience, preceded by a khuṭbah (a sermon as a technical replacement of the two reduced rakaʿāt of the ordinary ẓuhr (dhuhr) prayer), and followed by a congregational prayer, led by the imam. In most cases the khaṭīb also serves as the imam. Attendance is strictly incumbent upon all adult males who are legal residents of the locality.

The muezzin (muʾadhdhin) makes the call to prayer, called the adhan, usually 15-20 minutes prior to the start of Jum'ah. When the khaṭīb takes his place on the minbar, a second adhan is made. The khaṭīb is supposed to deliver two sermons, stopping and sitting briefly between them. In practice, the first sermon is longer and contains most of the content. The second sermon is very brief and concludes with a dua, after which the muezzin calls the iqama. This signals the start of the main two rak'at prayer of Jumu'ah.
