Al-Ala al-Hadhrami

Al-Ala al-Hadrami (Arabic: العلاء الحضرمي, romanized: al-ʿAlāʾ al-Haḍramī; died 635–636 or 641–642) was an early Muslim commander and the tax collector of Bahrayn (eastern Arabia) under the Islamic prophet Muhammad in c. 631–632 and Bahrayn's governor in 632–636 and 637–638 under caliphs Abu Bakr (r. 632–634) and Umar (r. 634–636). Under Abu Bakr, al-Ala suppressed a rebellion by a scion of the pro-Sasanian Lakhmid dynasty as part of the Ridda wars. Under Umar, he launched naval expeditions against the Sasanians, the last of which ended in disaster for the Arabs and was the cause of his dismissal. He was last appointed governor of Basra but died on his way there to assume office.
