ABSTRACT
El-Mansur’s troubles did not end with the defeat of ‛Abdullah and the murder of Abū Muslim. The rebellious Mesopotamians, under their leader Mulabbab esh-Shaybāni, more than once repulsed the troops sent against them by the Caliph, and not till a.h. 138 (755) was order restored by Khāzim ibn Khuzayma. 1 In the meantime a “ Magian,” or Zoroastrian of Nīshāpūr, named Sinbad, 2 disgusted at the murder of his patron Abū Muslim, rose in rebellion to avenge the blood of the fallen general. 3 He soon found himself at the head of a large following, 4 and gained possession of Nīshāpūr, Kūmis, and Ray. In the town last mentioned the treasure which had been left there by Abū Muslim fell into his hands. Against him El-Mansūr despatched Jahwar 5 ibn Marrār el-‛Ijlī, at the head of 10,000 men, who encountered and put to flight the rebels between Hamadān and Ray. Sinbad escaped from the field of battle, but was overtaken and killed between Tabaristān and Ray, his revolt having lasted just seventy days. 6
