How many of the Abyssinians embraced Islam after the emigration of Muslims to Abyssinia?

The number of Abyssinians who embraced Islam when Muslims migrated to them was not specified. However, Islam entered Abyssinia with the arrival of Muslims, and their king, the Negus, embraced Islam, which indicates that others with him also became Muslim. This is further evidenced by Asma bint Umays suckling the Negus's son, and some of the Abyssinians who had embraced Islam would come to her to inform her of their news.
