The data were primary data obtained through questionnaires. The questionnaire consisted of question items on Islamic spirituality, workplace spirituality, organizational commitment and OCBIP. The data analysis technique was partial least squares (PLS). Findings Islamic spirituality is not directly influencing toward OCBIP, spirituality at work and organizational commitment as moderation variables in the influence of Islamic spirituality toward OCB IP, OCBIP had influence toward working performance. Higher OCBIP would result in better working performance accepted, and at the opposite, lower OCBIP would result in poorer working performance. Originality/value There are some limitations of previous studies that examine spirituality relationships with OCB. Nasrudin et al. (2013) and Kazemipour et al. (2012) found significant correlations between spirituality with OCB, but there is an inconsistency of research findings to suggest that spirituality has no direct effect on OCB, but through individual perceptions of organization. As the study of spirituality with OCB is still limited, this study attempts to explain OCB from an Islamic perspective, to propose a framework on Islamic spirituality, spirituality at work as an individual source of OCB and moderation of organizational commitment using Djafri and Noordin’s (2017) and previous empirical studies, with an aim to integrate the spirituality and OCB in a model that can be used to better understand OCB. It is hoped that this model development will reduce the scarcity of literature on spirituality with OCB through organizational commitment. This will help the organization to understand the role of spirituality and organizational commitment to improve OCB of employees that ultimately will improve organizational performance.
