Muslim scholars have defined ethics as enduring traits and characteristics in the individual that cause actions appropriate to those traits to be issued spontaneously without the need for human thought and reflection. Islamic ethics state the rightness or wrongness of these attributes within the framework of Islamic concepts, while the concepts of Islamic work ethics deal with the functioning of the framework of Islamic concepts in the form of human work activities in various organisations. Furthermore, work ethics can be effective (...) in the organisation when it can shape the culture of the organisation. Research shows that Islamic work ethics have a significant relationship with various individual, professional and organisational factors. The purpose of this study is to investigate the relationship between Islamic work ethics and organisational culture. The statistical population of this research consists of 1500 Muslim staff of 30 service organisations (financial, educational, medical and hotel organisations) in Moscow, Russia, in 2021, of which 306 people have been selected as statistical samples using Krejcie and Morgan's sample size table. Data analyses were performed by statistical software, Statistical Package for the Social Sciences (SPSS). The results of this study confirm the significant and positive relationship between Islamic work ethics and organisational culture among the Muslim Russian staff (β = 0.53; T = −8.65). CONTRIBUTION: This study examines the relationship between Islamic work ethics and organisational culture in Russia and has expanded the results of previous studies conducted in other contexts.
