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.
Sudanese Arabs
Sudanese Arabs are the majority population of Sudan. They are predominantly Muslim and most of them speak the Sudanese Arabic dialect. The population of Sudan also includes various tribes who are genealogically Arabian, such as the Shaigiya,Ja'alin, Shukria, Juhaynah,Rashaida, Sulaym etc. (according to Johann Ludwig Burckhardt, the Bedouins of the eastern desert of Sudan, such as the Ja'alin and Shaigiya are almost indistinguishable from the Bedouins of eastern Arabia).
