Shah Cheragh is a funerary monument and mosque in Shiraz, Iran, housing the tomb of the brothers Ahmad and Muhammad, sons of Imam Musa Kazem and brothers of Imam Reza (Mashhad). The two took refuge in the city during the Abbasid persecution 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.
The site is the most important place of pilgrimage within the city of Shiraz. Ahmad came to Shiraz at the beginning of the third Islamic century (approximately 900 AD), and died there.
