I want to know the answer to the following question:
What state employed Abmad ibn Ibrahim al-Ghazi?
All the background I'm provided with is that "whose general Ahmad ibn Ibrahim al-Ghazi (Ahmed Gurey) was the first commander to use cannon warfare on the continent during Adal's conquest of the Ethiopian Empire, and the Sultanate of the Geledi, whose military dominance forced governors of the Omani empire north of the city of Lamu to pay tribute to the Somali Sultan Ahmed Yusuf.". Is that enough to answer the question?
Answer: no
