قتيبة بن مسلم الباهلي
In 726 Asad rebuilt the city of Balkh, which had been destroyed by Qutayba ibn Muslim following a revolt, and transferred there the Arab garrison troops from nearby Barukhan. Asad also resumed, after almost a decade, the practice of sending envoys to the Chinese court. This move was clearly linked to the Türgesh threat, as the Turks were Chinese vassals and were regarded by the Transoxianians as the agents of the Chinese emperor, sent to deliver them from Arab rule. Asad is also said to have built the village of Asadabad near Nishapur, which his descendants held until Tahirid times.
