Fearing the increasing power of the Abbasid general [[Abu Muslim]], who had gained popularity among the people, al-Mansur carefully planned his assassination. Abu Muslim was conversing with the Caliph when, at an appointed signal, four (some sources say five) of his guards rushed in and fatally wounded the general.<ref name= Marigny1758>{{cite book|last1=Marigny|first1=François Augier de|title=The history of the Arabians, under the government of the caliphs, from Mahomet, their founder, to the death of Mostazem, the fifty-sixth and last Abassian caliph; containing the space of six hundred thirty-six years.

The execution of Abu Muslim caused uproar throughout the province of [[Khorasan Province|Khorasan]]. In 755 [[Sunpadh]], an Iranian nobleman from the [[House of Karen]], led a revolt against al-Mansur, taking the cities of [[Nishapur]], [[Qumis, Iran|Qumis]], and [[Ray, Iran|Ray]]. In Ray, he seized the treasures of Abu Muslim. He gained many supporters from [[Jibal]] and [[Tabaristan]], including the [[Dabuyid]] ruler, [[Khurshid of Tabaristan|Khurshid]], who was paid with money from the treasures.<ref name= Marigny1758 />{{rp|201}} Al-Mansur ordered a force of 10,000 under Abbasid commander Jahwar ibn Marrar al-lijli to march without delay to Khorasan to put down the rebellion. Sunpadh was defeated, and Khorasan was reclaimed by the Abbasids.<ref name= Marigny1758/>

Al-Mansur sent an official to take inventory of the spoils collected from the battle as a precautionary measure against its distribution to the army. Angered by al-Mansur's avarice, Jahwar gained support from his troops for his plans to split the treasures evenly, and revolted against the caliph. This raised alarm in the caliph's court, and al-Mansur ordered Mohammad ibn Ashar to march towards [[Greater Khorasan|Khorasan]]. Jahwar, knowing his troops were at a disadvantage, retired to [[Isfahan]] and fortified in preparation. Mohammad's army pressed the rebel forces, and Jahwar fled to [[Azerbaijan]]. Jahwar's forces were defeated, but he escaped Mohammad's pursuit. This campaign lasted from 756 to 762 CE (138 to 144 AH).<ref name= Marigny1758 /> In 759, al-Mansur sent an army under his generals [[Abu al-Khaṣīb Marzuq]] and [[Khazim ibn Khuzayma al-Tamimi|Khazim ibn Khuzayma]] to Tabaristan to punish Khurshid for his support of Sunpadh. Khurshid was defeated and Abu al-Khasib was appointed as the governor of the region.<ref>{{Cite book |last=Malek, Hodge M. |url=https://books.google.com/books?id=zqY0AAAACAAJ |title=The Dābūyid Ispahbads and Early 'Abbāsid Governors of Tabaristān: History and Numismatics |date=2004 |publisher=Royal Numismatic Society |isbn=978-0-901405-83-8 |language=en|page=14}}</ref>

After relieving former vizier ibn Attiya al-Bahili, al-Mansur transferred his duties to Abu Ayyub al-Muriyani from [[Khuzestan]]. Abu Ayyub had been a secretary to Sulayman ibn Habib ibn al-Muhallab, who in the past had condemned al-Mansur to be flogged. Abu Ayyub had rescued al-Mansur from this punishment. Nevertheless, after appointing him as vizier, al-Mansur suspected Abu Ayyub of various crimes, including extortion and treachery, which led to the latter's assassination. The secretary role was granted to Aban ibn Sadaqa until the death of the caliph al-Mansur.<ref name=Al-Masudi/>{{rp|26}}
