- Before passing to the time of Mahomet it is necessary to take account of three other Arabian powers, those of Hira, Ghassan and Kinda.
The kingdom of Hira (Hira) was established in the boundary land between the Euphrates and the Arabian desert, a district renowned for its good air and extr a ordinary fertility.
The chief town was Hira, a few miles south of the site of the later town of Kuf a.
The inhabitants of this land are said in Tabari's history to have been of three classes: - (s) The Tanukh (Tnuhs), who lived in tents and were made up of Arabs from the Tehama and Nejd, who had united in Bahrein to form a new tribe, and who migrated from there to Hira, probably at the beginning or middle of the 3rd century A.D., when the Arsacid power was growing weak.
(2) The `Ibad or `Ibadites, who dwelt in the town of Hira in houses and so led a settled life.
