Al-Muthanna ibn Haritha managed to force the upcoming Persian army to cross the river to a place where his soldiers, who were divided into
brigades, could encircle their numerically superior opponents. The war ended with a huge success for the Muslims, thanks in no small part to the help of local Christian Arab tribes who decided to help the Muslim army. According to Tabari, the Persian leader Mihran bin Badhan was killed by a slave, Jabir bin Abdullah, who belonged to the Taghlab tribe and two masters, Jarir and Ibn Hober (later, a dispute ensued between the masters regarding the sharing of Mehran's weapons and clothing which had to be resolved by Al-Muthanna). The Arabs gained the momentum to further expand their wars against the Sassanids and their allies. ==Historicity==
