A prophet/advisor of Amano's escaped Amda's approach and continued to speak out against him and Ethiopia. A chronicle of Amda's reign called The Glorious Victories says:
The false prophet fled to the land of Ifat and lived there propagating his false teaching... And when Sabr ad-Din asked him for council he told him saying: "The kingdom of the Christians has now come to an end; and it has been given to us, for you will reign on in Siyon [i.e. Ethiopia]. Go, ascend [the mountains], and fight the king of the Christians; you will defeat him, and rule him together with his peoples."
You took away the commodities belonging to me obtained in exchange for the large quantity of gold and silver I had entrusted to the merchants... you imprisoned the traders who did business for me.
Sabr's rebellion was a grandiose plan to not just shake off Ethiopia's rule, but to conquer Ethiopia completely. He boasted:
"I wish to be King of all Ethiopia; ... I will destroy their churches...I will nominate governors in all the provinces of Ethiopia,...I will transform the churches into mosques. I will subjugate and convert the King of the Christians to my religion, I will make him a provincial governor, and if he refuses to be converted I will hand him over to one of the shepherds, ... that he may be made a keeper of camels. As for the Queen Jan Mangesha, his wife, I will employ her to grind corn.
Amda Seyon met the approaching Muslim army and scattered them. Sabr fled and hid. Amda promised not to return to his kingdom until he had found Sabr and dealt with him. The Ethiopians destroyed Fiat's capital, plundered it of anything precious, and killed many men, women, and children.
Sabr ad-Din sent a message to Amda's queen, Jan Mengesha, but she upheld her husband's vow not to return until Sabr had been found and dealt with. Sabr realized the only way to end the conflict was to surrender himself to Amda. Rather than execute Sabr, Amda had him imprisoned, and then appointed Sabr's brother, Jamal ad-Din, as Amda's governor in Ifat. Jamal urged Amda to stop ravaging Ifat, and let his people rebuild so that they could send their tribute to Amda.
Amda's soldiers also wanted to return home, but Amda had other uprisings to deal with from Muslims to the east. The story of Glorious Victories continues tomorrow.
