Abstract Prior studies suggest that knowledge about workers' psychological well‐being is overly focused on materialism or biologically‐based understanding, not taking into account the role of spirituality in one's well‐being. Drawing on Ryff's (1989) psychological well‐being framework and using an interdisciplinary approach, this paper offers a model of 'well‐being in Islam' through theorizing this concept from an Islamic lens and contextually studying the implications of Islamic practices and spiritual facilities for employees' psychological well‐being in workplaces. Drawing on qualitative data collected from 22 employees, our model (findings) shows that worshipping Allah, contemplative practices, and patience are key elements of one's well‐being. This paper also points towards the important role of specific spiritual provisions (e.g., designated rooms for prayer, prayer time and ablution facilities) and contemplative practices (e.g., ritualistic‐cyclic, creative process, generative, movement practices, stillness, activist, relational) for Ryff's six dimensions of employees' eudaimonic well‐being. This study is unique as it integrates the notion of well‐being in Islam into management and organization studies and offers a novel and contextual extension of Ryff's theory by integrating a spiritual notion of well‐being. In the end, theoretical and practical implications are offered.
