The dome atop the prayer hall symbolizes heaven and provides practical benefits like carrying the imam's voice and keeping the hall cool. The minaret allows the call to prayer to be heard from afar and helps people locate the mosque. The prayer hall contains no chairs as worshippers kneel and prostrate on carpets, with men and women separated. The mihrab indicates the qibla direction of Makkah. Prayer mats contain symbols like the mihrab arch to guide correct worship orientation. Calligraphy from the Qur'an decorates walls in place of images.
