A monumental inscription runs along the top of the courtyard's walls, above the openings of the iwans, and features a verse of the Qur'an (3:190-192, from the Surah Ali 'Imran[9]).[2] The iwans had richly painted and gilded wooden ceilings, with the ceiling of the southern iwan being well-preserved and restored today.[3][4] The southeastern iwan is the qibla iwan (the one pointing in the direction of prayer) and features a mihrab which, along with the surrounding wall, is decorated in multi-coloured marble.[2]
