Arab Muslims (Arabic: العرب المسلمون) are adherents of Islam who identify linguistically, culturally, and genealogically as Arabs. Arab Muslims greatly outnumber other ethnoreligious groups in the Middle East and North Africa. Arab Muslims thus comprise the majority of the population of the Arab world. Not all citizens of Arab-Muslim majority countries identify as Arab Muslims; many Arabs are not Muslim and many Muslims are of non-Arab ethnicity. Arab Muslims form the largest ethnic group among Muslims in the world, followed by Bengalis, and Punjabis.
