Firuzabad (Fars)

Firuzabad (early Islamic Jur), in the Fars region of southwestern Iran, was an ancient circular city, the early Sasanian capital of Ardashir I, that continued as a town in the Islamic period. The Shafi'i jurist Abu Ishaq al-Shirazi (d. 1083), author of the legal manuals al-Tanbih and al-Muhadhdhab and a leading teacher at the Nizamiyya of Baghdad, took the nisba al-Firuzabadi from this town in Fars.
