Ismāʿīl ibn Ṣāliḥ ibn ʿAlī al-Hāshimī (Arabic: إسماعيل بن صالح بن علي الهاشمي) was an eighth century Abbasid governor of Egypt and Aleppo.
A member of the Abbasid family, he was a son of Salih ibn Ali[1] and a first cousin of the first two Abbasid caliphs al-Saffah (r. 750–754) and al-Mansur (r. 754–775). During the reign of Harun al-Rashid (r. 786–809) he was appointed as governor of Egypt in 797. After an administration lasting slightly less than a year, he was dismissed from that province[2] and instead posted to Aleppo and Qinnasrin, which he proceeded to hold for an unspecified length of time.[3]
^The latest possible date for the end of his Aleppine governorship is 802. Cobb 2001, pp. 142, 156; Ibn al-Adim 1996, p. 105. Ibn al-Adim goes on to say that Isma'il later served as governor of Damascus, but Cobb was unable to find any corroborating sources for this claim.
