In Islam, Friday prayer, or Congregational prayer, is a special community prayer service held once a week instead of the afternoon Zuhr prayer in Salah the daily prayer ritual and one of the Five Pillars of Islam. All Muslim men are expected to participate at a mosque with certain exceptions due to distance and situation. Women and children can also participate but do not fall under the same obligation that men do. The service consists of several parts including ritual washing, chants, recitation of scripture and prayer, and sermons.

Imam is an Islamic leadership position. For Sunni Muslims, Imam is most commonly used as the title of a prayer leader of a mosque. In this context, imams may lead Islamic prayers, serve as community leaders, and provide religious guidance. Thus for Sunnis, anyone can study the basic Islamic sciences and become an Imam.
