Jumu'ah is the Friday congregational prayer that replaces Dhuhr for Muslims who attend the weekly mosque service.
It is held around the time of the ordinary midday prayer and includes a khutbah, or sermon, before the prayer itself. The congregational service is traditionally associated with a mosque, although Islamic legal details concerning attendance, eligibility, and minimum congregation differ among schools.
Jumu‘ah is not simply an additional prayer added to Dhuhr. For those required to attend and who perform it, it takes the place of the regular Friday midday prayer. Women, travelers, the sick, and others may have different legal obligations depending on circumstances and interpretation.
