The historian al-Umari, records that it was near the Red Sea coast, and states its size as 15 days travel by 20 days travel; its army numbered 15,000 horsemen and 20,000 foot. Al-Umar also credits it with seven "mother cities": Belqulzar, Kuljura, Shimi, Shewa, Adal, Jamme, and Laboo. Modern historians believe its borders included Fatagar, Dawaro and Bale; this gave Ifat control of the trade route inland from Zeila, making it a major commercial power.
Despite this victory, revolts from the Muslim people of Ifat continued. In the early 15th century, the Ethiopian Emperor branded the Muslims of the surrounding area "enemies of the Lord" and invaded Ifat. The Ifat armies were crushed once and for all and their king, Sa'ad ad-Din, fled to Zeila; the Emperor pursued and the king was killed. The sources disagree which Emperor conducted this campaign: according to the medieval historian al-Makrizi, in 1403 Emperor Dawit pursued the Sultan of Adal, Sa'ad ad-Din II to Zeila where he killed Sa'ad ad-Din, and sacked Zeila; however, another contemporary source dates the death of Sa'ad ad-Din to 1415, and gives the credit to Emperor Yeshaq.
Ifat eventually disappeared as a distinct polity following the invasion of Ahmad Gragn, and the subsequent Oromo migrations into the area. Its name is preserved in the modern Ethiopian district of Yifat in the Oromia Region.
