There are places that are not allowed for Muslims nor Christians to build up their religious houses and openly practice their religions?

But in any other Muslim dominant areas, non-Muslims are free to do that. Here in Qatar, there are lots of houses that have been use for religious studies/prayers and gatherings. 2 houses in the same area of my home here is a house for religious/bible studies. So where is the problem which had been asked by Dmighty? Don't think, the authority is not aware of that, sure they are....and I dont think its illegal here?
