Hejazi Arabic
Hejazi Arabic or Hijazi Arabic ( '), also known as West Arabian Arabic, is a variety of Arabic spoken in the Hejaz region in Saudi Arabia. Strictly speaking, there are two main groups of dialects spoken in the Hejaz region, one by the urban population, originally spoken in the major cities of Jeddah, Mecca and Medina, and another by the Bedouin or rural populations. However, the term most often applies to the urban variety which is discussed in this article.
Sudan
Sudan has 597 groups that speak over 400 different languages and dialects. Sudanese Arabs are by far the largest ethnic group in Sudan. They are almost entirely Muslims; while the majority speak Sudanese Arabic, some other Arab tribes speak different Arabic dialects like Awadia and Fadnia tribes and Bani Arak tribes who speak Najdi Arabic; and Rufa'a, Beni Ḥassān, Al-Ashraf, Kinanah and Rashaida who speak Hejazi Arabic. In addition, the Western province comprises various ethnic groups, while a few Arab Bedouin of the northern Rizeigat and others who speak Sudanese Arabic share the same culture and backgrounds of the Sudanese Arabs.
