This paper explores how Muslim healthcare chaplains understand and navigate diversity from their professional positions. In a context shaped by societal categorizations of 'good' and 'bad' diversity, chaplains often mediate between institutional frameworks, patient needs and their own theological principles. Focusing on their daily interactions with patients, families and healthcare teams, the paper examines how Muslim chaplains navigate and conceptualize diversity concerning cultural, religious and linguistic differences. By reviewing their experiences, the paper sheds light on the challenges and opportunities of managing diversity in hospitals, highlighting the importance of reflective practice and intercultural competence. The paper contributes to wider reflections on how diversity is constructed, contested, and experienced in contemporary spiritual care settings by focusing on the evolving role of Muslim chaplains in contemporary healtcare contexts.
