Did d'Awa Conquer Abyssinia?

Islam did not make a strong presence just by D'Awa in this land of Abyssinia. They did of course convert Najashi, did they convert anybody else a Lahua Island? Maybe they did. There are some reports that indicate maybe there were some Muslims in Abyssinia but there wasn't any large presence of Islam until Islam came back to Abyssinia and conquered it as a political power.
