Abstract
This text is a narrative that shows the fluid border between religion and culture, from my own observation at the Islamic community in Portugal. Despite the differences and complexities found in the group of Muslims in Portugal, due to its origins, to Islamic movements and strands, the Guinean Muslims will be the protagonists in this article, especially because it is a case of continuing migration in that country, which results in increase of that population in Portugal. In a way, this finding helps illustrate the fluidity of relationships religion / culture, by the very practices from their particular cultures. In addition, as a Muslim majority, which comes from the same geographical region, reproducing ethnic traits, undergo a process of segregation, not only by the wider host society but also by the Islamic religious group based in Portugal, which is generating a conflict situation
