Arab

An Arab is a person whose native language is Arabic, whether born in the Arabian Peninsula (Arabia) itself, or in the northern part of Africa, known as the Maghreb, or indeed wherever Arabic is the native language. Many, but not all, Arabs are Muslims (there are many Lebanese Christians, for example) and of course by no means all Muslims are Arabs - though the holiest sites in Islam are in Saudi Arabia, which occupies most of the Arabian Peninsula.
