Hamdanid dynasty
The reason for Husayn's execution is unclear. The historian of the Hamdanid dynasty, Marius Canard, suggested that it may have been due to his involvement in a Shi'a-inspired conspiracy, possibly connected to the dismissal of Ibn al-Furat from his second vizierate during the same period, or with the rebellion of the autonomous governor of Adharbayjan, Yusuf ibn Abi'l-Saj, whom al-Muqtadir may have suspected of ties with the imprisoned Husayn. As Canard writes, "in any case the caliph must have feared that if Husayn were released he would once again start a revolt, either through a desire for independence or as a Shi'i. In order to avoid attempts by those (probably numerous) who desired his release to secure it by force, the caliph preferred to take a measure which put a stop to all intrigue".
