Sulaymān ibn ʿAlī al-Hāshimī (Arabic: سليمان بن علي الهاشمي) (c. 700–759) was an early Abbasid prince.
[2] In 750–1 he was appointed by al-Saffah as governor of the important post of Basra in southern Iraq together with its dependencies, as well as a number of other provinces including the Tigris districts, Bahrayn, Oman and Mihrajanqadhaq.
[4] During his administration of Basra, Sulayman carried out extensive public works projects to develop the region, including building new canals and making improvements the local water supply.
[5] He also assisted Khazim ibn Khuzayma al-Tamimi during the latter's campaign against Kharijite rebels in Oman in 750–1 by providing him with ships to transport his army,[6] and in 754 he allowed his brother Abd Allah take refuge in Basra after the failure of his rebellion against al-Mansur.
He and Isa ibn Ali eventually delivered their brother to al-Mansur on the condition that his life be spared, but this agreement was quickly violated and the caliph surreptitiously put Abdallah to death.
