If you're in the mood to go "shopping" for a religion, Singapore is one of the best places to do it. It's a surprisingly religous nation, but not comprosed of a dominant one like so many other countries (read: USA and Christianity). From what I could tell in the few days there, there's a large Islamic, Buddhist, Hindu and Christian population and they all play seemingly equal parts in Singaporian culture. Admittedly, I've never been exposed to Hinduism or Islam, apart from the superficial things like pictures, movies and strangers on the street who wear the clothes. Even though I've never fell for the media hype in the States that likes to typecast Muslims as "terrorists," I also never had any desire to seek a deeper understanding of them either. Thankfully, Singapore is the first place I've ever been to where Muslims made up a large part of the population.
Without getting to much into it. i was suprised to learn that Allah is essentilly the same God that Christians pray to. The fundamental difference is that they don't believe in the Holy Trinity or Jesus as the son of God. They do believe that he is a divine prophet though and that Mary was divine as well. Both religions demand that worshippers commit themselves to their one God. I know I only got a superficial glance at Islam, but it's not as different from Christianity as I previously thought.
