The Jumma Mosque, also known as Masjid al-Jumah, is located in Medina, Saudi Arabia. It is situated in the northwest corner of the city, near the site where the Prophet Muhammad is said to have performed the first Jumu'ah prayer after his migration from Mecca to Medina.

The mosque has a simple rectangular design, with a prayer hall and a courtyard. It can accommodate up to 5,000 worshippers at a time. The mosque has undergone several renovations over the years, with the latest one taking place in the 1990s.

The Jumma Mosque is an important site for Muslims, as it is one of the earliest mosques built after the Prophet Muhammad's arrival in Medina. It is also significant because the Friday prayer, or Jumu'ah, is considered a congregational obligation for Muslim men, and the mosque serves as a gathering place for this weekly prayer.

If you plan to visit the Jumma Mosque, it is advisable to dress modestly and remove your shoes before entering the prayer hall.
