He had completed primary school but, through independent study, he became fluent in English and acquired a good knowledge of labour law.
There he came to the attention of a very influential man in the city named Rashid al-Haj Ibrahim, who employed Taha to work in the Arab Chamber of Commerce.
In 1937, during the 1936–39 Arab revolt in Palestine, he was detained by British forces for six months without trial under the Defence (Emergency) Regulations.
[2] Taha joined the Palestine Arab Workers Society (PAWS) — which was established in 1925 — where he was employed as a low level clerk then a secretary.
The assailant was not apprehended, but it is known that he was killed on the orders of Haj Amin al-Husseini, the Grand Mufti of Jerusalem and leader of the Palestine Arab Party.
