Ridda wars
In mid-September 632, Abu Bakr dispatched Hudaifa bin Mihsan's corps to tackle the apostasy in Oman, where the dominant tribe of Azd had revolted under their chief Laqeet bin Malik, known more commonly as "Dhu'l-Taj" ("the Crowned One"). According to some reports, he also claimed prophethood.

Hudaifa entered Oman, but not having sufficient strength to fight Dhu'l-Taj, he requested reinforcements from the Caliph, who sent Ikrimah from Yamamah to aid him in late September. The combined forces then defeated Dhu'l-Taj at a battle at Dibba, one of Dhu'l-Taj's strongholds, in November. Dhu'l-Taj himself was killed in the battle.

Hudaifa was appointed governor of Oman, and set about the re-establishment of law and order. Ikrimah, having no local administrative responsibility, used his corps to subdue the area around Daba, and, in a number of small actions, succeeded in breaking the resistance of those Azd who had continued to defy the authority of Medina.
