The purpose of this paper is to examine the role that religion plays in the working lives of Muslim employees, by exploring the influences of Islamic values on employees Organisational Citizenship Behaviour. This is a largely quantitative study conducted in Jordanian organisations. The study introduces a theoretical model drawing parallels between Organisational Citizenship Behaviour and Islamic Work Ethics. The participants, comprising of employees of Jordanian public and private sectors, have been randomly invited to express their views on the possible penetration of Islamic values in the workplace. A Partial Least Squares approach alongside a bootstrapping technique was used to analyse the data. The validity of the measurement model was tested using the Fornell and Larcker criterion. Findings indicate that Islamic values do influence the citizenship behaviour, organisational commitment and loyalty to the organisation of employees. Motivated by religion employees are more likely to adopt discretionary citizenship-alike behaviours in the workplace and be loyal to their organisation. The scope of this study is limited by its primary focus of developing an Islamic perspective within the domain of Organisational Citizenship Behaviour, which utilises the Islamic Work Ethics framework rather than being grounded in Islamic holy texts. This paper not only provides a useful insight into the link between religious motivation, citizenship behaviour, and organisational commitment and loyalty, but also notes the influence of religion in the workplace.
