أحمد بن إبراهيم الغازي
Abu Bakr organized Somali troops, then attacked Sultan Garad Abun ibn Adash of Adal and killed him, making himself sultan. However, his control over Adal was disputed by Imam Ahmad ibn Ibrahim al-Ghazi, who eventually defeated Abu Bakr and killed him. The Imam then made his own brother, Umar Din, the new Sultan.
