Al-Ala ibn al-Hadrami

Al-Ala ibn al-Hadrami (Arabic: العلاء بن الحضرمي, romanized: al-ʿAlāʾ ibn al-Haḍramī; died 635–636 or 641–642) was an early Muslim commander, the tax collector for Bahrayn (eastern Arabia) under the Islamic prophet Muhammad in c. 631–632, and governor of Bahrayn 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 to assume office.
