[1] The mosque is named after a local saint, Muhammad ben Salah (or Ibn Salih) to whom it is dedicated and around whose tomb it was built.

[2][3] As of 2012, there were plans to convert the madrasa into a museum displaying religious objects from the city's heritage, such as minbars and manuscripts.

The interior features a rectangular courtyard, wide but not very deep, surrounded by arcades and centered around a small basin or fountain.

Beyond the courtyard is the main space of the prayer hall, defined by two rows of arches forming nine aisles.

The top of the minaret, including its upper lantern, is rimmed with merlons typical of Moroccan architecture.

The building is centered around a large square courtyard, surrounded by a two-story gallery leading to numerous rooms.
