Michigan is 1-2% Muslim overall. That includes blacks and the NOI, which are relatively strong in some of the inner cities.
Some of the sky is falling stuff here is ridiculous.
Dearborn, Michigan now has the largest single concentration of Arab Muslims in North America. There are 32,000 Arab Muslims from Lebanon, Yemen and Iraq living in East Dearborn, making up almost 1/3 of the population. In some districts it is common to see store signs and billboards written in Arabic.
Shi’a Mosque
The Islamic Centre of America in Dearborn, a Shi’a mosque frequented mostly by Lebanese Muslims, is the largest mosque in the US. The Centre’s attractive website has several good photos: http://www.icofa.com/.
Mosques and Islamic Centres play an important role in the life of American Muslims. They are places of refuge and of rest; places where a Muslim can experience the Islamic community and learn about Islam. Many Muslims feel safer and more relaxed within the centres which are somewhat isolated from outside influences. Dearborn is one of the few places in the US where one can actually hear the call to prayer publicly over a loudspeaker.
