Adud al-Dawla Qubad was the Baduspanid ruler (ustandar) of Rustamdar from 1379 to 1381.
[1] The son and successor of Fakhr al-Dawla Shah-Ghazi, Qubad was soon after his accession accused by the Mar'ashis of being uncooperative and mistreating the dervishes of their order.
[1] A year later (1381), a Mar'ashi force defeated and killed Qubad at a battle at Laktor.
The fortress of Kojur was conquered and made the permanent residence of Fakhr al-Din; the Mar'ashis were now the masters of all of Mazandaran.
The Baduspanids were temporarily ousted from power, until almost a decade later in 1390, when the Mar'ashis installed Sa'd al-Dawla Tus on the Baduspanid throne in Rustamdar to challenge the Afrasiyabid prince Iskandar-i Shaykhi who accompanied the Turco-Mongol ruler Timur (r. 1370–1405), who intended to conquer Mazandaran.
