He then left for Tehran. With Agha Mohammad once again in the north, Jafar Khan began raising an army to prepare another attack against Isfahan and its surroundings. When Ali Qoli found out about it, he sent a group of tribesmen to a city south to Isfahan, named Qumishah. However, Jafar Khan managed to easily defeat them. Ali Qoli thereafter retreated to Kashan. Agha Mohammad Khan, learning of this, rapidly marched towards Isfahan, which made Jafar Khan withdraw to Shiraz once again. Agha Mohammad Khan, who was too unconfident to try and capture Shiraz, then went back to Tehran. Jafar Khan was murdered on 23 January 1789 by Ali Murad Khan's son Sayed Murad Khan. After his death, a four-month civil war began between several Zand princes who fought for succession to the throne. Jafar Khan's son Lotf Ali Khan emerged being the victor in this civil war in May.
