Al-Sindi ibn Shahak (died 819) was a late 8th-century Abbasid general and administrator who served as the governor of Syria, Damascus and Baghdad under al-Mansur, Harun ar-Rashid and al-Amin.
As the head of shurta (military police), he oversaw the destruction and confiscation of properties belonging to the Barmakids during the reign of Harun.
[2] He was a client (mawali) of Abbasid caliph al-Mansur, and served as governor of Syria during his reign.
[3] In 792 or 793, he was sent by Harun al Rashid to quell the revolt of Abū al-Hadhām in Damascus as commander of Khurasani troops, where he is mentioned as governor for Musa ibn Isa.
[8][5] Shi'a traditions also held him responsible for death of seventh Shia Imam, Musa al-Kazim in 799[9] and Yahya ibn Abdallah, a rebel Alid leader in 803.
