As Thomas already pointed out in his answer you might consider using 
amenity=place_of_worship as this is not exclusively reserved for churches. The 
OSM wiki has this paragraph concerning that key

    If the place of religious services is located in a /part of a multi-purpose
    building/, then the tag amenity
    <http://wiki.openstreetmap.org/wiki/Key:amenity>=*place_of_worship* should
    be placed on a node or area, inside the building outline. Examples are
    prayer rooms in public buildings or rooms rented for religious purposes in
    commercial buildings.

If the prayer house serves more like a cultural or social centre, using 
amenity=community_centre sounds like a viable alternative.

I am tempted to suggest using amenity=townhall. Reading the wiki:

    Use this for a village, town or city *townhall*, a building where the
    administration of a village, town or city may be located, or it may just
    serve as a community meeting place .

    A townhall is not necessarily used (or having ever been used) for
    administrative function. The tag is also used for a "village hall", commonly
    in UK villages, and used for community events such as fundraising and Discos.

Apparently, the administrative function is not a requirement for this tag.

> Quartier

http://wiki.openstreetmap.org/wiki/Tag:boundary%3Dadministrative proposes 
admin_level=10 for a quartier in CAR

I was just browsing the wiki, but have no prior experience concerning these 
topics. Hope this helps nevertheless.

Best Regards
