Sabr ad-Din III (Arabic: الصبر الدين الثاني) (died 1422 or 1423) was a Somali Sultan of Adal and the oldest son of Sa'ad ad-Din II. Sabr ad-Din returned to the Horn of Africa from Yemen to reclaim his father's realm. He defeated the Ethiopians and proclaimed himself "King of Adal". He subsequently became the first ruler and founder of the new Adal dynasty.
He returned from Arabia with ten horsemen, as well as military supplies provided by his family's patron Nasir Ahmad. Sabr ad-Din and his brothers made their way to the Somali city of Siyara, where they were joined by a number of their fathers former followers. Even though they were outnumbered by the soldiers of the Christian state, they fought several successful battles. Defeating them at the Battle of Zikr Amhara (Memory of the Amhara), also at the Battle of Serjan. Scattering their enemies, they burnt houses and churches and seized much booty in gold and other valuables.
Such destruction and opposition on the eastern borders angered the Christian rulers of the empire. An unnamed commander with ten chiefs, in charge of 20,000 men, moved into area for a year hoping to restore the lost "Amhara rule". This caused Sabr Ad-din and his followers to flee and endure hunger, thirst and other deprivations.
The Muslims forces later regained their strength. Sabr ad-Din was able to send his brother Muhammad with Harb Jaush, a defector from the Christian side, to attack the imperial forces. The Emperor's commander and many other Christian leaders fell at the Battle of Retwa and their soldiers were killed, except for a few of them who managed to escape. Sabr ad-Din seized a considerable amount of booty, then subsequently ruled the district for some time. He later proceeded towards the Emperor's headquarters, where the Battle of Adal was fought in which many Christian nobles fell, after which Sabr ad-Din put their headquarters up in flames.
Victorious the King then returned to his capital, but gave the order to his many followers to continue and extend the war. He entrusted his brother Muhammad with the task of capturing a fort at Barut and then instructed one of his commanders, Omar to raid the land of Jab. This was so well defended by the imperial forces as by their sheer number as Maqrizi relates as "numerous as locusts", Omar's men were all killed by spears. Sabr Ad-Din was almost captured but escaped because of the speed of his horse.
Sabr-ad-Din soon died of natural death, in 1422-3[1] [2]
