Muhammad ibn Sulayman ibn Ali ibn Abdallah ibn Abbas (Arabic: محمد بن سليمان بن علي بن عبدالله بن عباس‎; c. 740–789) was a member of the Abbasid dynasty who served as provincial governor of Kufa and Basra and its dependencies in the Persian Gulf for most of his life. He also played a leading role in the suppression of the pro-Alid uprisings of 762–763 and 786, and helped ensure the peaceful accession of Caliph al-Mahdi in 775. His enormous fortune was confiscated after his death by Caliph Harun al-Rashid.
