In 1012, the al-Hakem Edict was issued, under which all Jews and Christians in Palestine were ordered to either convert to Islam or leave. This led to the majority of non-Hebrew origin Christians (i.e., foreign Christians) to leave Palestine, while over 90 per cent of Jews, Samaritans (also of Hebrew origin) and Hebrew-origin Christians converted and became Muslims. They would also become Musta'arabim (Arabized), acculturated into Arab language, custom and culture.[10]
