伊嗣俟三世
Around 650, Yazdegerd III, along with Farrukhzad, arrived to Khorasan. Yazdegerd III then appointed Farrukhzad as the governor of Merv and ordered Baraz, the son of Mahoe Suri, to give absolute control of the city over to him. Mahoe, however, disobeyed him. Farrukhzad then advised Yazdegerd III to take refugee in Tabaristan. Yazdegerd III, however, did not accept his advice. Farrukhzad later made a mutiny against Yazdegerd III and left for Ray, to avenge his father against Siyavakhsh, who was the ruler of the city. On his way to Ray, he met his ally Kanadbak, who was part of the conspiracy against Khosrow II and had taken part in Rostam's clash with the Arabs, but after the defeat had fled to Tus, a city which was part of his domains. Farrukhzad then continued his journey to Ray, but before reaching the city met the Arab general Nu'aym near Qazvin in 651, whom he made peace with.
