Taym Allah (also transliterated Taymallah), known as Taym Allat (also transliterated Taymallat) in the pre-Islamic period or before their conversion to Christianity, were an Arab tribe in eastern Arabia and the lower Euphrates valley, belonging to the Banu Bakr confederation. They were a relatively minor branch and most of their pre-Islamic history pertains to their role in the Lahazim alliance of Bakrite tribes in the alliance's conflicts with the Tamim tribe and the Lakhmids, the main Arab vassals of the Sasanian Empire. They fought against the Muslims during the conquest of Iraq, but afterward embraced Islam and eventually, a number of their tribesmen held important military positions in the eastern provinces of the Caliphate. A small section of the tribe settled the Wadi al-Taym valley, which is called after them, in modern Lebanon.
