During Abbad's governorship of Sijistan, Ubayd Allah served as governor in Iraq and their brother Abd al-Rahman served as governor of Khurasan.[1] Abbad was replaced in 681 when Yazid put Khurasan and Sijistan under the authority of Abbad's brother, Salm,[3][4] who in turn appointed another brother, Yazid, as his deputy in the province.[3] This chronology, according to the 8th-century historian Umar ibn Shabba is disputed by the information in Tarikh-i Sistan and 9th-century historian al-Yaqubi, which holds that Ubayd Allah appointed Yazid before 681.[2] In any case, Ubayd Allah informed Abbad of the developments, and in reaction to his dismissal, Abbad divvied up the funds of Sijistan's treasuries among his slaves and Arab troops before departing the province.[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.[8] In response to Yazid's inquiry regarding the treasury sums Abbad was expected to bring the caliph, he stated that he was obliged to pay the large number of troops under his authority as would be expected of him, in such a critical frontier region as Sijistan.[8]
