Purpose: The purpose of this study is to investigate the influential factors of customer loyalty to Islamic banks, namely, service quality, customer satisfaction, customer engagement and religiosity. Design/methodology/approach: This study is a survey of 335 Islamic bank customers in West Sumatra, Indonesia. This research deployed purposive sampling and analyzed the data by using covariance-based structural equation modeling. Findings: Service quality has a positive and significant impact on customer satisfaction. Religiosity has a significant and negative moderating impact on the service quality–customer satisfaction relationship. Service quality has no significant influence on customer loyalty. Customer satisfaction is a significant antecedent of customer engagement and loyalty. Finally, customer engagement has a significant and positive effect on customer loyalty. Research limitations/implications: This study is a combination of cross-sectional and a single-country case. Accordingly, the results may not be representative of other countries. Similar studies in longitudinal data collection are conducted in other countries (e.g. ASEAN countries), which would therefore be worthwhile. Some antecedents of customer loyalty have been neglected in this study (e.g. customer value co-creation and customer commitment); hence, the future study may investigate those factors. Practical implications: By considering these Islamic banks’ antecedents, the Islamic banks might enhance their customer loyalty. Also, this study has revealed the moderating role of religiosity in a loyalty relationship. Therefore, it will give insights for the Islamic bank managers in decision-making. Originality/value: This study has revealed the moderating role of religiosity on the link between service quality and customer satisfaction in Islamic banks, which is, to the authors’ knowledge, neglected in the previous studies. The customers with high religiosity will have a higher standard of satisfaction and demand a better service quality than the customers with low religiosity. This study has also examined the relationships between service quality, religiosity, customer satisfaction, customer engagement and loyalty as a whole, which have been limited previously.

The research aimed at finding out the relationship between Halal tourism, religiosity, customer engagement, and tourist’s satisfaction. The population of the study were Muslim tourists who visited West Sumatra, Indonesia. The data were 450 respondents, but only 393 were useable responses. It is found that Halal tourism and customer engagement have significant impacts on the tourist’s satisfaction. Religiosity is a significant moderating variable on this relationship. Thus, this study gives some contribution to tourism sector especially on Halal tourism, religiosity, and customer satisfaction.

The concept of Halal tourism has emerged recently in research. It becomes an important factor in determining the satisfaction of tourists or their loyalty. However, this concept is still not well known; thus, it needs to be developed in certain areas. The research was conducted to see the link between the attributes of Halal tourism (i.e. Islamic facility, Halalness, general Islamic morality, and alcohol drinks- and gambling-free), satisfaction of tourists and word of mouth (WOM). The respondents of the research were 345 derived from 5 municipals in West Sumatera, Indonesia. The research used structural equation model. The result of the research shows that the attributes of Halal tourism have significant impacts on satisfaction of tourists and WOM. There is no significant direct relationship between the attributes of Halal tourism and WOM. However, the satisfaction of tourists is significant as the mediator. Furthermore, some limitations and future research are discussed.

Purpose: This paper aims to examine the impact of religiosity on Muslim-friendly destination performance, customer engagement and customer satisfaction; the mediating impact of Muslim-friendly destination performance, customer engagement and customer satisfaction on the link between religiosity and word of mouth (WOM); and the moderating impact of religiosity on the relationship between Muslim-friendly tourism, customer engagement and customer satisfaction. Design/methodology/approach: The population of this study was all tourists who visited West Sumatra Indonesia. By using a survey through questionnaires, this study has got 393 out of 450 collected responses (83.6%). This research used the structural equation modeling as the data analysis technique. Findings: This research found that religiosity is a significant antecedent of Muslim-friendly tourism, customer engagement and tourist satisfaction. This study revealed that Muslim-friendly tourism, customer engagement and tourist satisfaction significantly mediate the link between religiosity and WOM. This research also found that religiosity significantly moderates the effect of Muslim-friendly tourism on tourist satisfaction. Research limitations/implications: This study was only conducted in Indonesia; hence, it lacks generality. Accordingly, future studies can expand to several other countries such as Southeast Asian countries which have big Muslim population. This study only focused on Muslim-friendly tourism industry as a whole. For future studies, it can be extended to several related industries, such as hotel, food and beverage and halal cosmetic. Practical implications: This study has shown the important of manager knowledge about religiosity of customers. Accordingly, when they want to increase tourists’ WOM, they have to increase tourist perceived quality of Muslim-friendly tourism attributes which also have an impact on customer engagement and tourist satisfaction. Originality/value: This study proposes the direct relationship between religiosity and Muslim-friendly tourism, the religiosity-customer engagement link and the religiosity-tourist satisfaction relation. This research has revealed the mediating effect of Muslim-friendly tourism, satisfaction and engagement on the link between religiosity and WOM. This study has also revealed the impact of religiosity in strengthening the link between halal tourism and tourist satisfaction which is limited previously.

This study aims to investigate the influence of environmental and non-environmental factors on tourist satisfaction in halal tourism destinations in West Sumatra. The environmental factor is perceived environmental value. Meanwhile, non-environmental factors are halal-friendly destination performance, sustainability tourism development, and halal destination image. The survey was conducted by distributing questionnaires to 690 respondents who visited halal tourism destinations in West Sumatra. It was analyzed by using the Structural Equation Modeling (SEM)—Partial Least Square (PLS). The results indicate environmental factors (perceived environmental values) and non-environmental factors (halal-friendly destination performance, sustainable tourism development, and halal destination image influence tourist satisfaction. Moreover, sustainability tourism development mediates the effect of perceived environmental value on tourist satisfaction. However, sustainability tourism development does not mediate the effect of halal-friendly destination performance on tourist satisfaction. Meanwhile, the halal destination image does not moderate the effect of sustainability tourism development on satisfaction. Thus, our research can be used as a reference for tourist destination managers to increase tourist satisfaction by maintaining and managing the tourist destination environment properly.

Purpose: This study aims to examine the relationship between trust and its antecedents, i.e. customer satisfaction, perceived value and religiosity. The moderating roles of religiosity on the relationships between perceived value, satisfaction and trust also have been investigated in this study.Design/methodology/approach: This research has carried out in West Sumatra Indonesia. The respondents of this study are Islamic bank customers from five areas in West Sumatra Indonesia. Data have been collected through Survey method. After some preliminary analyses, we employed 390 useable responses in the analysis. Covariance Based Structural Equation Modeling (CB-SEM) was employed to analyze the data.Findings: This study found that religiosity has significant impacts on perceived value, customer satisfaction and trust. Perceived value and customer satisfaction are also significant antecedents of trust. Moreover, it found the significant moderating impact of religiosity on the link between perceived value and trust, and also on the link between customer satisfaction and trust.Research limitations/implications: This cross-sectional study has been conducted in a single country. Accordingly, this study may have a limitation in result generalization. Moreover, this study only focused on three antecedents of trust, including religiosity, satisfaction and perceived value. Therefore, for future research, we suggest conducting a longitudinal study in some Muslim countries such as Malaysia, Brunei Darussalam and Middle East countries. We also suggest employing other antecedents of customer trust, such as customer engagement and customer sociocultural.Practical implications: Based on the research findings, the managers of Islamic banks will have input on how to improve their customers' trust by giving more attention to customer religiosity, perceived value and satisfaction. They can develop programs to increase customer perceived value and satisfaction such as a reward program to increase customer trust.Originality/value: A more comprehensive model of the relationship between religiosity, perceived value, satisfaction and trust has been addressed in this study. This study also highlighted the significant moderating role of religiosity on the link between perceived value, satisfaction and trust which are neglected previously have also been highlighted in this study.
