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.
The Taym Allah are reported to have fought alongside their Bakrite tribesmen against the al-Hira-based Lakhmids, Arab client kings of the Sasanian Empire,[1] including at the famed Battle of Dhi Qar in 611 CE.
[4] The Taym Allah, and the largely Christian, core tribes of the Lahazim in general, appear to have fought against the Muslim conquests of eastern Arabia in the Ridda wars (632–633) and the lower Euphrates in modern Iraq afterward.
They are then found in the ranks of the Christian Ijl chief Abu al-Aswad when he and a local Sasanian garrison fought the Muslims at the Battle of Walaja in Iraq.
A member, Iyas ibn Abd Allah, played a role among the Muslim rebels who killed Caliph Uthman in Medina in 656.
At the time, the Caliphate was in middle of the Second Muslim Civil War, with Mus'ab representing the Mecca-based Zubayrid side against the Syria-based Umayyads.
[9] The founder of the Hanafi madhhab (Islamic school of jurisprudence), Abu Hanifa (d. 767), was sometimes given the tribe's epithet, 'al-Taymi', because his grandfather had been a freed mawla (client) of the Taym Allah.
