Oman (عمان) officially the Sultanate of Oman (سلطنة عُمان), is an Arab country on the southeastern coast of the Arabian Peninsula in Western Asia. Recent excavations in the Dhofar Governorate more than 100 surface scatters of stone tools, belonging to a regionally specific African lithic industry—the late Nubian Complex—known previously only from the northeast and Horn of Africa, were found. This supports the proposition that early human populations moved from Africa into Arabia during the Late Pleistocene.
The People of 'Ād (قوم عاد), according to tradition were Arab and lived in south of Arabia. They were descendants of 'Ad b. 'Aws who named their tribe after their forefather. They are mentioned in various Surah of the Qur’an, after the people of prophet Nuh (Noah). Most of the narrative is mentioned in the Surah Hud. It is believed that the remains of an ancient city found by the amateur archaeologist Nicholas Clapp were those of the city mentioned in Quran.
