Al-Ala al-Hadhrami

Under Abu Bakr, al-Ala suppressed a rebellion by a scion of the pro-Sasanian Lakhmid dynasty as part of the Ridda wars.

Al-Ala was dispatched by the Islamic prophet Muhammad to collect the tax from the inhabitants of Bahrayn (eastern Arabia) in late 631 or early 632.

The first caliph (Muhammad's successor as leader of the Muslim community) Abu Bakr (r. 632–634) dispatched al-Ala to reinforce Mundhir's supporters and suppress the rebellion.

[7] Al-Ala's operations against the settlements of Bahrayn continued into late 634, during the reign of Abu Bakr's successor Umar (r. 634–644).

The Arab force was withdrawn from the island possibly due to the disapproval of Umar, who was opposed to naval campaigning.

[13] Upon receiving news of the situation in the Persian Gulf, Umar issued orders condemning and dismissing al-Ala from the governorship of Bahrayn and the Yamama in 638.
