If you happen to visit Hospitals in the United States, you will see Interfaith chapels in each hospital. These chapels could be used by all religions and denominations even by atheists and agnostics. I have seen the Muslims, Christians and Hindus, Buddhist praying in the same chapel. A Muslim is saying his prayers, a Buddhist monk is doing his meditation and a Christian is saying his private prayers in the same chapel. It is a very common in the United states. God bless you America.
