Karen brought this thread to my attention. I can explain a bit about mosques.

Mosques don't have benches or pews. Muslims pray 5 times a day (before sunrise, noon, afternoon, sunset, and night), and prayers take place in congregation at every mosque around the world at all 5 times. It is our 'link' to our Creator, and a daily reminder to connect with, and thank God for all of His blessings. You do not 'have to' pray every prayer at the mosque (you can pray anywhere....at home, at work, in a parking lot, wherever.....the prayers are mandatory), but many people try their best to make it as much as possible. We don't have anything at the mosque other than a big hall and carpet. In the front of the hall is a podium for the imam to give sermons. That's about it. Most mosques keep stacks of chairs for the elderly/or those who need them, but generally, all we need at a mosque is a clean, empty hall. We go to the mosque to pray to God, the One who created us, and to do that, we do not need anything other than ourselves, and a pure heart. It really is, just a big empty room. This is how we pray.
