High Quality Content by WIKIPEDIA articles! Umar Din (r. 1526-1553) was a sultan of Adal and brother of Abu Bakr ibn Muhammad. Umar Din was made sultan by Imam Ahmad ibn Ibrihim al-Ghazi after he killed Umar Din's brother Abu Bakr in 1526, and ruled at least until the Imam was killed in battle in 1542. Although Trimingham describes the Sultan as the Imam's puppet, the Futuh al-Habasa of Sihab ad-Din records that the Sultan and the Imam quarrelled over the distribution of the alms tax at some point between the Battle of Shimbra Kure and the Battle of Amba Sel, which led to Imam Ahmad leaving Harar to live amongst the Somalis in Zarba for some time. This suggests Umar Din wielded some power of his own.
