The purpose of the study is to investigate how teachers describe their teaching on Islam and which didactic opportunities and challenges there are when teaching Islam in religious education. The study is based on qualitative semi-structured interviews with six religion teachers in high school. Because of covid-19 the interviews were conducted through phone calls. The study is based on a hermeneutic theory which means the teachers experiences, attitudes and feelings is of relevance for answering the questions.   The result has a thematic arrangement and below each theme the informants’ answers are presented regarding how they experience their opportunities and challenges when teaching. The primary opportunities are reflected in the theme inside perspective because teachers can use a variety of strategies to look at Islam from the inside. Also, there is very modern material about the religion that can be applied to stimulate discussions in the classroom. The challenges are considerably more but the main once are to counteract prejudice and selecting textbooks that do not represent Islam in negative terms as the informants’ express.
