Peninsular Arabic
Peninsular Arabic, or Southern Arabic, are the varieties of Arabic spoken throughout the Arabian Peninsula. This includes the countries of Saudi Arabia, Yemen, Oman, United Arab Emirates, Kuwait, Bahrain, Qatar, Southern Iraq and the tribal people of Jordan (the native Jordanians).
Sudanese Arabs
While most Sudanese Arabs speak some form of Sudanese Arabic, some other Arab tribes speak different Arabic dialects like the Awadia and Fadnia tribes and the Bani Hassan, Al-Ashraf and Rashaida who speak Hejazi Arabic. In addition, Western province tribes like the Baggara and Darfurians) speak Chadian Arabic, although they have great variation in cultural and genealogy aspects. Sudanese Arabs descend primarily from migrants from the Arabian Peninsula and some of the pre-existing indigenous populations of Sudan, most predominantly the Nubian people who also share a common history with Egypt. In addition, a few Arabian tribes existed in Sudan prior to the advent of Islam. Nevertheless, most Arab tribes migrated into the Sudan in the 12th century and introduced Islam.
