As cliché as it sounds, its Prophet Muhammas saw. He is the Messenger of Allah. He is the teacher to his people. He is also the leader of human beings, including all races. He is the bearer of good news. Pembawa berita gembira.
What good news? Good news are the news of what he had been doing 1400 years ago. Tell people to spread peace and love by loving (and believing that) The Only One God, Allah and follow the Prophet's teachings and do good deeds, be nice to people. Allahu akbar.
Indeed, what a role model he is.
