The Army of the Holy War or Holy War Army (Arabic: جيش الجهاد المقدس; Jaysh al-Jihād al-Muqaddas) was a Palestinian Arab irregular force in the 1947–1948 civil war in Mandatory Palestine led by Abd al-Qadir al-Husayni and Hasan Salama. The force has been described as Husayni's "personal" army. The Arab League set up the Arab Salvation Army (Jaysh al-Inqadh al-Arabi) as a counter to the Army of the Holy War while, in practice, the Arab governments prevented thousands of volunteers from joining either force.
Abd al-Qadir al-Husayni arrived in the Jerusalem sector in December 1947 and by March 1948 had about 128 men. He established his headquarters at Bir Zeit and started to conduct a blockade of Jerusalem by attacking the Jewish convoys to the city. Hasan Salama, with 950 men of the Jihad and 228 irregulars, took responsibility for the operations in the Lydda and Ramle sectors, at the entry of the Tel Aviv-Jerusalem road.
