Najashi and the Muslims of Abasinia

al-bayhakki narrates in his sonan sorry in his uh dar al-nubuah that the prophecies him eventually wrote him a letter when he emigrated to medina. The muslims live there for more than ten years and unfortunately we don't have very many stories of abasinia. There's only one story involving a pretender to the throne not an internal struggle within the palace no another force. Another abasinian royal family was struggling with the najashi and trying to seek power in the land.
