I'm not very familiar with the Muslim faith; most people in my state are Christian. However, in the past few years, we've had several thousand Somalis relocated here. Now, people in my state can be very provincial in their attitudes, and distrustful of people from outside our state. So, we've got a bunch of folks who are: not from Maine, not from the U.S., not white, not Christian, and who, at least in the beginning, did not speak our language. Oh, and the Somali women wear very distinctive clothing, including headscarves. We were prepared for all sorts of anti-Somali, anti-Muslim talk from the locals. Amazingly, though, after a period of adjustment, everyone seems to be getting along just fine.
One of the larger companies up here has hired a large number of Somalis- for custodial and factory jobs at first, then other jobs as they learned sufficient English. A group of Somali men who worked in the warehouse were washing their feet in the men's restroom before they prayed. This got water all over the floors, and their co-workers were upset with the mess. Someone in management took the trouble to get someone bilingual to ask the Somali men what the deal was with all the water. On discovering it was a religious practice, the company installed a special room with foot-baths for them. By all accounts, it's not at all fancy, nor did the company spend all that much money on it. But it was a simple gesture to ease tensions between both parties, and it's done the trick. The other workers have not seen this concession as an example of favoritism, or as a repudiation of the Christian faith, nor should they! It's just a convenience for all concerned.
