I want to know the answer to the following question:
According to al-Umari, how many cavalry did the Sultanate of Ifat have?
All the background I'm provided with is that "The Sultanate of Ifat, led by the Walashma dynasty with its capital at Zeila, ruled over parts of what is now eastern Ethiopia, Djibouti, and northern Somalia.". Is that enough to answer the question?
