This study explores whether, and how, mindfulness mediates the relationship between spiritual leadership and human engineering. Based on data from a sample of 335 members of faculty and administrative staff from Imam Mohammad Ibn Saud Islamic University in Saudi Arabia, the paper provides insights into how mindfulness affects the relationship between spiritual leadership and human engineering. The authors believe that it is the first time that mindfulness as a mediator in this relationship has been studied. They also believe that it is the first time such a study has been conducted in an Arab environment. By studying the relationship between spiritual leadership and human engineering, and by studying mindfulness as a mediating variable in this relationship in a non-Western environment, the study expands the external validity of the notions of spiritual leadership and human engineering. The results indicate a significant relationship between spiritual leadership and human engineering, and show that mindfulness has an indirect effect on this relationship. The article highlights the implications for dealing with stress in the work environment by using mindfulness as a driver for developing spiritual leadership, as well as understanding and practicing the values of spiritual leadership in promoting spirituality.
