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 Beni Ḥassān, Al-Ashraf, Kawhla 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.
