After Sultan Muhammad ibn Nasir departed from the city to wage war against the Ethiopian Empire, the Oromos had launched one of the most devastating attacks ever mounted on Harar, a local Harari chronicle states: When the Galla knew that the Muslim army had gone to Abyssinia they devastated the land of Sa’adin and destroyed a hundred Muslim villages.
The trench failed and the Galla broke the defense system of the city.
It was in this battle that wazir Hamid was wounded with a spear twenty times.
With his new Somali troops Mansur was able to easily repel several Oromo attacks on Harar.
He then went to Zeila and Aussa with 150 Somali calvarymen and reestablished control over those areas.
