Masjid Aqsab (ar|مسجد الأقصاب), also called Masjid al-Qasab, is a neighborhood and district of the Sarouja municipality of Damascus, Syria. It had a population of 14,148 in the 2004 census.[1] The neighborhood was founded during the Mamluk era (14th century) as a suburb of the walled city of Damascus, bordering the Bab al-Salam gate to the south and contiguous with the al-Faradis neighborhood to the west.[2] It was built around the Aqsab Mosque, after which the neighborhood was named. The mosque purportedly contained the graves of seven Sahaba (companions of Muhammad).[2] In the 1936 French Mandate census, the neighborhood had a population of 6,900, all Muslims.[3]
