Muhammad Jadallah "Abu Nihad" is a Jerusalemite freedom fighter who was born on 17 May 1921 in the village of Sur Baher and attended several schools until he finished high school. Afterwards, he began his work as a waiter in several places, the last of which was before the 1948 Arab-Israeli War at the King David Hotel in Jerusalem. When he reached the age of twenty-six, the Higher Arab Committee in Palestine, in cooperation with the Palestinian Arab Party in Jerusalem, selected him and others from several regions to send them for military training in Syria, in coordination with the League of Arab States. In the summer of 1947, Jadallah arrived at the Qatanna camp in the Syrian territories, received his military uniform and completed registration and discipline procedures according to the Liberation Army's requirements. The warrior returned to Jerusalem and trained the people of his village in shooting and using weapons. After that, he joined the Fourth Company of the "Third Regiment", with the rank of first lieutenant.
