Sabr ad-Din I (flourished 1332) was an amir of Ifat, the son of Nahwi bin Mansur bin Umar Walashma and younger brother of Haqq ad-Din I. Sabr ad-Din rallied his fellow Muslims in a counteroffensive in early 1332 against the Ethiopians; however, the Emperor of Ethiopia Amda Seyon I defeated him in battle, then invaded a number of Muslim kingdoms, including Dawaro and Bale, which brought an end to the independent kingdoms of Hadiya, Fatagar, Dawaro, and Ifat. Sabr ad-Din was captured with his ally king Haydara of Dawaro, and who were imprisoned together. The Emperor Amda Seyon appointed as his successor his brother Jamal ad-Din I.
