Did any White Europeans convert or revert to Islam during the Prophet Muhammad's time or early on after his death I know there were Black Africans during the Prophet Muhammad's time who accepted Islam but did any Greeks Romans or any other Europeans accept Islam since they ruled the Middle East at one time ? I ask this question because I am a White Western person and many Whites in the West think White people can't be Muslims when I have met White Muslims.
