'Ali remained loyal to Timur, dying in 1386 after being wounded during Timur's campaign in Lesser Luristan. As a reward for this loyalty, Timur never occupied Sabzavar with his own troops, and allowed 'Ali to retain his local administration. After 'Ali's death, the Sarbadar territories were split amongst his relatives, who mostly remained loyal to Timur as well and took part in his campaigns. Muluk Sabzavari did become involved with the revolt of Hajji Beg of the Ja'un-i Qurban (which had been forcibly submitted to Timur's rule around 1381) in Tus in 1389, and afterwards sought refuge with the Muzaffarid Shah Mansur in Isfahan, but was eventually pardoned by Timur and given the governorship of Basra near the end of 1393. That same year, following the conquest of Baghdad by Timur, the governorship of that city was given to 'Ali's nephew Khwaja Mas'ud Sabzavari, who had a force of 3,000 Sarbadars. Despite this, he was forced to retreat in 1394 when Sultan Ahmad of the Jalayirids marched to recapture the city, and he retreated to Shushtar. Following the death of Timur, the Sarbadars slowly fell out of prominence.
