[1][3] While the historian Muhammad Abdulhayy Shaban notes that Sijistan remained stable under Abbad's rule with no record of rebellions in the province or military expeditions originating from there,[3] the historian K. V. Zetterstéen asserts that Abbad was an active participant in the eastward expansion of the Caliphate and credited him with leading the conquest of Kandahar.
[5] Abbad detained him for a short period, but Ibn Muffarigh continued to insult his erstwhile patron's family in verse after he was released.
He was captured and humiliated in public by Ubayd Allah in Basra and sent back to Abbad who kept jailed him until he was released by the caliph's intervention in 680.
[7] On his way back to report to Caliph Yazid in Damascus, Abbad avoided encountering Salm when passing through the vicinity of Jiroft in Kirman.
[4] Following the decisive Umayyad victory in the battle, Abbad sought to retire to the north Arabian oasis town of Dumat al-Jandal, but was dispatched by Caliph Abd al-Malik to confront a commander of the Kufa-based, pro-Alid rebel leader al-Mukhtar al-Thaqafi at some point prior to 687.
