Al-Hasan was the son of Fairuzan, a Daylamite soldier who, along with his brother Kaki, served the Alid dynasties of northern Iran.
Makan had established family ties through marriage with the Alids, as Ja'far, the son of imam Hasan ibn Ali al-Utrush (r. 914–917), was his son-in-law.
[1][3] Muhammad, however, managed to escape from his captors and with the aid of the Gilaki military chief Asfar ibn Shiruya, who had seized control of Gurgan, defeated the two brothers and retook his throne.
A fake rumor later spread about the death of Makan,[4] which made al-Hasan, who wanted to install his half-brother Ismail as the imam, rise into rebellion.
However, the rebellion failed after Ismail was poisoned at the instigation of Abu Ja'far Husayn's mother.
Relations between Makan and Vushmgir improved to the point where the former felt secure enough to drop his dependence on the Samanids.
He also had a daughter who married Rukn al-Dawla, and bore him three sons named Abu'l-Hasan Ali, Buya ibn Hasan, and Fanna Khusraw.
