Introduction
Arabia was the birthplace of the Islamic religion; the Arabic language was the "tongue of the angels," since God chose to reveal himself through that vehicle to Prophet Muhammad peace be upon him, the founder of the faith. Arabia would become the center of the Islamic world, and the source of renewal and inspiration for the faithful believers throughout an emerging Islamic empire.
Arabia
Arabia before the birth of Prophet Muhammad peace be upon him had been a culturally isolated and economically underdeveloped region. The Arabian peninsula is one-third the size of the continental United States. Most of the land is arid and desert; rainfall is scarce, vegetation scant, and very little of the land is suitable for agriculture. In the north of the region, several Arabic kingdoms were able to establish contacts with the Byzantine and the Persian Sassanian empires as early as the fifth century A.D. To the south, small Arabic kingdoms, including Saba (Sheba), were ancient centers of Arabic civilization. But in the interior, dotted only with occasional oases, the nomadic life was the only successful existence.
