Shah Cheragh Mosque
Shāh Chérāgh is a funerary monument and mosque in Shiraz, Iran, housing the tomb of the brothers Ahmad and Muhammad, sons of Mūsā al-Kādhim and brothers of ‘Alī ar-Ridhā. The two took refuge in the city during the Abbasidpersecution of Shia Muslims.
The tombs became celebrated pilgrimage centres in the 14th century when Queen Tashi Khatun erected a mosque and theological school in the vicinity.
Shāh-é-Chérāgh is Persian for "King of the Light". The site was given this name due to the nature of the discovery of the site by Ayatullah Dastghā'ib (the great grandfather of the contemporary Ayatullah Dastghā'ib). He used to see light from a distance and decided to investigate the source. He found that the light was being emitted by a grave within a graveyard. The grave that emitted the light was excavated, and a body wearing an armor was discovered. The body was wearing a ring saying al-‘Izzatu Lillāh, Ahmad bin Mūsā, meaning "The Pride belongs to God, Ahmad son of Musa". Thus it became known that this was the burial site of the sons of Mūsā al-Kādhim.
