Muʿādh ibn Muslim—then governor of Khurasan—along with the commander Jibrīl and Layth, the freedman of al-Mahdī, were dispatched. The fortress itself lay within the district of Kash ⦗1⦘. The siege dragged on for almost two years. When the accursed impostor realized that destruction was at hand, he swallowed poison and gave the same poison to his womenfolk; they all died. The stronghold was seized, his head cut off, and it was sent aloft on a spear to al-Mahdī in the year 163 AH. It reached the caliph at Aleppo while he was mustering the armies for a campaign against the Byzantines together with his son Hārūn al-Rashīd; it proved to be a momentous expedition ⦗2⦘.
