Al Jum'ah Mosque, Historical mosque in Medina, Saudi Arabia.

Al Jum'ah Mosque is a prayer house in Medina with one large central dome and four smaller domes at the sides. The renovated building holds about 650 worshippers and has separate prayer sections for men and women, plus a library.

The building marks where Prophet Muhammad led his first Friday prayer in 622 during his migration from Mecca to Medina. Over time the structure changed from its original stone form into the building that stands today.

Locals also call it Masjid Bani Salim, after the Banu Salim ibn Awf of the Ansar who lived in this area, and Masjid al-Qubayb after the spot where it was built. The first Friday sermon Muhammad gave here opened with the words "al-hamdu lillah, ahmaduhu wa asta'inuhu".

The mosque lies on Wadi Ranuna', about 900 m north of Quba Mosque and roughly 2.3 km from Al-Masjid an-Nabawi, so it is usually visited on the road between the two. The 1988–1991 rebuilding added a women's prayer room, bathrooms, an imam's residence and a Quran school. Visitors should dress modestly and time a visit outside Friday prayer, when the 650-place hall fills.

Two rectangular white marble slabs flank the entrance door, inscribed in interlaced script with a foundation order naming the Ottoman Sultan Bayezid II, who ruled 886–918 AH. The text records his command to build this mosque, dated to Shawwal. Look for the panels set into the wall beside the arched doorway.
