This dissertation examines frameworks of orientation within mosque communities based on communal conflict lines and areas of tension. The study follows a qualitative-reconstructive approach. Through problem-centered interviews, mosque members, imams, and (youth) group leaders were interviewed, allowing for a comparison between two diametrically opposed mosque communities and the reconstruction of their collective frameworks of orientation. The first community is a turkish DITIB-affiliated mosque. The second community is an umbrella-free, multinational, and German-speaking mosque. Mosque communities are institutionally embedded in specific contexts, which shape corresponding (re)orientations, (de)legitimations, visions, and ambivalences. Furthermore, fundamental milieu-specific demarcation lines emerge between the communities, influencing their respective approaches to preaching. Both mosques share the common practice of delivering Friday sermons, discussion circles, and religious education as central means of knowledge transmission. However, they follow completely different approaches in structuring and implementing these formats. While one community's actions are guided by migrant cultural heritage, the other exhibits a post-migrant cultural vision that significantly shapes its sermons and educational settings. This reveals how different institutional and socio-culturalexpectations placed on imams influence these settings. The comparison demonstrates how crucial the role of an imam is in determining how a community positions itself within both the local and broader society. In practical terms, imams play a key role in constructing a communal identity and communicating it to the wider society. This contribution will take a comparative approach, addressing selected aspects of the panel's questions based on insights from the dissertation.
