and inflicted a heavy defeat on him (30 September 737). However, later in the same year, Asad managed to inflict a heavy defeat on Suluk, who barely escaped capture and was forced to retire north to his lands. There he was soon after murdered by his rivals, leading to the collapse of Turgesh power amid civil war. In the aftermath of the battle, a certain prince named Badr Tarkhan, who may have been the ruler of Bamiyan, conquered Khuttal. Thereupon Asad invaded Khuttal and forced the principality to acknowledge Umayyad authority. In 750, the Umayyad Caliphate fell, and was replaced by the Abbasid Caliphate, who, under their general Abu Muslim Khorasani, sent Abu Dawud Khalid ibn Ibrahim, the governor of Balkh, to invade the region and bring it under direct Abbasid rule. When Abu Dawud invaded Khuttal, its ruler, known in Arabic sources as Hanash ibn al-Subul (also called Hubaysh ibn al-Shibl) did not resist the invasion, but the dehqans of Khuttal forcibly detained him and carried him to a fortress in order to fight Abu Dawud. Nevertheless, Abu Dawud managed to make Hanash and his dehqans leave the fortress. Hanash shortly fled to the court of the Turks, and then to the Chinese court, while Abu Dawud consolidated Abbasid rule in Khuttal, marking the end of the principality.
