For this, Emperor Amda Seyon ravaged Ifat and replaced Jamal ad-Din with his brother Nasr ad-Din.[3] The interpretation of this passage varies: Trimingham holds he joined the alliance of Mora and Adal in revolt against the empire, but they were defeated by the Emperor.[4] On the other hand, Taddesse Tamrat states that Jamal's rebellion never got that far, and he was recalled to the Ethiopian court and returned to prison on the pretext that he failed to find and bring to the Emperor all of the Christians who had converted to Islam. Jamal ad-Din alleged that the "son of his brother" (whom Taddesse Tamrat speculates might be the son of Sa'ad ad-Din) had prevented him from doing so.[5]
