Overview
al-Suyuti reports that in 195 AH al-Amin appointed Ali ibn Isa ibn Mahan over the mountain lands: Hamadhan, Nihawand, Qum and Isfahan. He left Baghdad in mid Jumada al-Akhira with forty thousand men to fight al-Ma'mun. 1
The battle
al-Ma'mun sent Tahir ibn al-Husayn against him with fewer than four thousand men, and the victory went to Tahir. Ali was killed and his army was routed. His head was carried to al-Ma'mun, who had it paraded through Khurasan, and he was greeted with the caliphate. 1
al-Suyuti relates that the news came to al-Amin while he was fishing, and he told the messenger to leave it, because Kawthar had caught two fish and he had caught nothing. 1
