Abd al-Rahim al-Hajj Muhammad (Arabic: عبد الرحيم الحج محمد ال سيف‎;1892 – March 1939), also known by his kunya Abu Kamal, was a prominent Palestinian Arab commander of rebel forces during the 1936–39 Arab revolt against British Mandate rule and increased Jewish settlement in Palestine. Most of his activities were based in the areas of Tulkarm, Nablus and Jenin (modern-day northern West Bank). In September 1938, he became the official General Commander of the Revolt, although he shared the post in rotation with Arif Abd al-Raziq. In February 1939, al-Hajj Muhammad was given sole title to the post by the revolt's political leadership, but was killed the following month in a firefight with British forces.
