Another writer, Ibn al-Faqih, reported that the Sasanian emperors kept a palace at a nearby place called Āzarmīḏdoḵt.

[5] Early Islamic Asadabad was a small but prosperous city in the province of Jebal, surrounded by fertile farmlands that produced cereals, cotton, fruit, and especially honey.

In 810-11, during the Fourth Fitna, a battle was fought at Asadabad between the forces of al-Amin and al-Ma'mun, two sons of the Abbasid caliph Harun al-Rashid.

Al-Ma'mun's general Taher Dhu'l-Yaminayn, who would later go on to found the Tahirid dynasty of Khorasan, defeated al-Amin's commander Abd-al-Rahman ibn Jabala Abnawi, who was killed in battle.

Another battle was fought at Asadabad in 1120, when Mas'ud ibn Mohammad, the governor of Mosul, al-Jazira, and Azerbaijan, unsuccessfully rebelled against the Seljuq emperor Mahmud II.
