As-Sajadah Mosque, Islamic worship center in northern Medina, Saudi Arabia.

As-Sajadah Mosque stands 900 metres north of Al-Masjid an-Nabawi in Medina. Its cream stone facade carries a tall pointed-arch window with dark glass and a small grilled window beside it, with two air-conditioning units mounted on the wall. A cylindrical cream minaret with two projecting balconies and a pointed conical top rises on the left, next to a large pale dome on a rectangular base and a smaller dome to its right.

The mosque is named As-Sajadah, "the prostration", for the account that Muhammad prostrated here in thanks after Gabriel brought him news that whoever invokes blessings on him receives God's blessings and peace in return, as reported by Ahmad in his Musnad. It is also called Asy-Syukr Mosque and, more commonly today, Abi Dzar Mosque, after the street it stands on. It was rebuilt and enlarged in the modern style in 1421 AH (2000 CE).

The name As-Sajadah ("the prostration") recalls the account that Muhammad prostrated here after Gabriel brought him news about salawat. Locals more often call it Abi Dzar Mosque, after the street it stands on, and the two names are used side by side in Medina.

The mosque stands on Abi Dzar Street, about 900 metres north of Al-Masjid an-Nabawi, a walk of roughly ten to fifteen minutes from the Prophet's Mosque. The 2000 renovation and expansion enlarged the prayer space. Visitors should dress modestly and avoid entering during congregational prayer unless joining it.

The mosque's better-known name, Abi Dzar Mosque, comes from Abi Dzar Street, where it stands; the name As-Sajadah recalls Muhammad's prostration of thanks here after Gabriel brought news about salawat. The 2000 renovation gave the complex its cream facade, tall pointed-arch window and two-balcony minaret.
