He remained governor until the death of al-Ma'mun in 833, at which point he decided to place Abbad ibn al-Ghamr al-Shihabi in charge of the province and departed for Iraq.^[2]

Abdallah was also a frequent leader of the pilgrimage, having led the annual events of 828, 829, 831, and possibly 832.^[3]
