I want to know the answer to the following question:
Who ordered that a hymn be composed that first mentioned the Somalis?
All the background I'm provided with is that "During the wars between the Sultanate of Ifat based at Zeila and the Solomonic Dynasty, the Abyssinian Emperor had one of his court officials compose a hymn celebrating a military victory over the Sultan of Ifat's eponymous troops.". Is that enough to answer the question?
