Hayyan's Treaty with the Ispahbadh

Yazid, who was Yazid ibn al-Muhallab, appointed Abd Allah ibn Ma'mar al-Yashkuri over Dahistan and al-Bayasan with four thousand men. He sent his son Khalid and his brother Abu Uyayna against the Isbahbadh, and they were defeated. ¹

The Isbahbadh wrote to the marzban to kill the Arabs with him, and Abd Allah ibn Ma'mar and his men were killed while they were off guard. Yazid sent Hayyan, a client of Masmala who was among the captives of the Daylam, to the Isbahbadh in Tabaristan. ¹

Hayyan told the Isbahbadh that he was a man of his people and that religion divided them. He kept on deceiving him until he made peace with Yazid for seven hundred thousand dirhams and four hundred qintars of saffron. They disagreed over the weight of the ten, and Hayyan made up the difference between the two weights. ¹

The source describes him as among the noblest and most distinguished of the clients, and gives his kunya as Abu Ma'mar. ¹
