The Banu Udhrah (Arabic: بني عذرة) was a Himyari Jewish tribe during the era of the Islamic Prophet Muhammad which converted to Islam after the Expedition of Ukasha bin Al-Mihsan in 627. During this expedition Muhammad ordered an attack on the Banu Assad bin Qhuzayma to capture spoils. The Battle of Tabouk took place in October 630  to attack the Byzantine empire. Mubarakpuri claims that the reason was revenge for the killing of one of Muhammad's ambassadors by a Christian chief of al-Balaqa, which led to the Battle of Mutah. Mubrakpuri claims this was also the reason for the Battle of Tabouk, and that there was a rumour that Heraclius was preparing an attack on the Muslims. William Muir claims Heraclius wanted to prevent the recurrence of Muslim attacks such as the Expedition of Ukasha bin Al-Mihsan against the Banu Udrah tribe. A tribe that was aligned to the Byzantine Empire
