GRAND RAPIDS, Mich.-From their cramped office behind a barber shop, four young men are trying to get the word out: This is who we are, this is what we believe. As Muslims in an overwhelmingly Christian community, they see it as their responsibility to tell what Islam truly teaches-to non-Muslims and other Muslims. They aim to do so through Sunnah Publishing, an educational nonprofit they formed four years ago. Hamza Kantarevic knows he looks exotic, and perhaps threatening, in conservative West Michigan. He and his colleagues at Sunnah Publishing hope to answer questions at their first public conference, “Islam in America,” beginning Friday, a few days before Ramadan begins. The seminar features Muslim scholars from Saudi Arabia, the United Kingdom and New Jersey addressing a wide array of topics, from what Islam teaches about violence and women to Muslim positions on intelligent design and the environment.
