The Arabs' control over Balkh did not last long as it soon came under the rule of a local prince, a zealous Buddhist called Nazak (or Nizak) Tarkhan. He expelled the Arabs from his territories in 670 or 671. He is said to have not only reprimanded the Chief Priest (Barmak) of Nava-Vihara but beheaded him for embracing Islam. As per another account, when Balkh was conquered by the Arabs, the head priest of the Nava-Vihara had gone to the capital and became a Muslim. This displeased the people of the Balkh. He was deposed and his son was placed in his position.
