The iwan of Sultan Hasan's mosque is richly decorated. A monumental inscription runs along the entire length of the iwan. The text is a fragment of the Surat al-Fath (Sura of Victory) from the Qur'an. Below this inscription band, the qibla wall is covered in multicolored marble paneling, centered around the mihrab which is framed by its own golden inscription and whose central half-dome hood features a sunrise motif radiating from the word "Allah".
