From a quick glance, the software - while being marketed as one for churches - isn't really religious. Accounts, profiles, timeline, photos, directories, attendance tracking - that's generic stuff not specific to churches. And verses are - technically - just articles.

From a quick glance it seems it could be fairly easily adapted for use even by non-religious organizations (say, clubs) with mostly basic UI text editing, so possibility of use by mosques seems even more trivial.
