appealed for aid against each other to Abu Muslim, who now held the balance of power. The latter eventually chose to support al-Kirmani. On 14 February 748, the Hashimi army occupied Marv, and Nasr again had to flee the city. Pursued by the Hashimi forces under Qahtaba ibn Shabib al-Ta'i, Nasr was forced to abandon Nishapur too after his son Tamim was defeated at Tus, and retreat to the region of Qumis, on the western borderlands of Khurasan. At this point, the long-awaited reinforcements from the caliph arrived, but their general and Nasr failed to coordinate their movements, and Qahtaba was able to defeat the caliph's army at Rayy and kill its commander. Nasr was now forced to abandon Qumis and flee towards Hamadan. On the way, in the town of Sawa, he fell ill and died on 9 December, at the age of 85. His grandson, Rafi ibn al-Layth, led a large-scale rebellion against the misgovernment of the Abbasid governor, Ali ibn Isa ibn Mahan, in 807–810, which spread across Khurasan and Transoxiana.
