ABSTRACT

This study presents a bibliometric analysis of the scholarly landscape surrounding Halal-friendly hospitality services, with a particular focus on industry practices. The rising demand for tourism services aligned with Islamic principles often referred to as Halal tourism, Islamic tourism, Muslim-friendly tourism, Halal travel, and Shariah-compliant tourism reflects a growing global awareness of the needs and expectations of Muslim travelers. Despite this surge in interest, there remains a lack of consolidated academic mapping of the field’s development, collaboration trends, and thematic directions. To address this gap, we conducted a comprehensive search using five targeted keywords across the Scopus database, yielding a total of 620 relevant documents published between 2004 and 2024. Data cleaning and refinement were performed using OpenRefine, while publication trends, subject areas, prolific authors, institutions, and countries were analyzed through the Scopus Analyzer. VOSviewer software was employed to visualize co-authorship networks, keyword co-occurrence patterns, and citation linkages, offering insights into the structure and evolution of the field. The results reveal a steady increase in research output over the last decade, with significant contributions from Southeast Asia and the Middle East. Keyword clustering analysis highlights dominant research themes such as Muslim traveler satisfaction, destination marketing, service quality, and religious compliance. Despite growing scholarly attention, collaboration among authors and countries remains relatively low, indicating a need for more integrated and interdisciplinary research. This study provides valuable insights for academics, policymakers, and industry practitioners seeking to understand current trends and future directions in Halal-friendly hospitality. It also highlights research gaps and opportunities to foster greater innovation and global engagement in this emerging tourism sector.

Keywords: Halal, Islamic tourism, Muslim-friendly, Halal travel, and Shariah-compliant

INTRODUCTION

The concept of halal-friendly hospitality services has gained significant traction in the global tourism industry, driven by the increasing demand from Muslim travelers seeking services that align with their religious beliefs. This sector, often referred to as Muslim-friendly or Shariah-compliant hospitality, encompasses a wide range of services including halal food, alcohol-free environments, prayer facilities, and accommodations that adhere to Islamic principles (Abas et al., 2017; Zawawi & Raml, 2017; Marzuki et al., 2019). The growth of this market is not only evident in predominantly Muslim countries but also in non-Muslim majority regions that aim to attract Muslim tourists by offering tailored services (Razzaq et al., 2016; Jung et al., 2024). This bibliometric study aims to explore the industry practices within halal-friendly hospitality services, highlighting the key attributes, challenges, and emerging trends in this evolving sector.

Halal-friendly hospitality services are characterized by several key attributes that cater to the needs of Muslim travelers. These include the provision of halal food, alcohol-free policies, prayer facilities, and the availability of Qibla direction in hotel rooms (Jung et al., 2024; Duman, 2019). Hotels often use Islamic symbols and images in their marketing to emphasize their compliance with halal standards, although many prefer to maintain a neutral impression to appeal to a broader audience (Muharam & Asutay, 2022). The implementation of these attributes is guided by standards such as the Malaysian Standard MS 2610:2015, which outlines the requirements for Muslim-friendly hospitality services (Abas et al., 2017; Zawawi & Raml, 2017).

Despite the growing demand, the halal-friendly hospitality sector faces several challenges. One major issue is the lack of standardized guidelines and certification processes, which can lead to confusion among service providers and consumers (Zawawi & Raml, 2017; Karim et al., 2022). Additionally, the high cost of transitioning to Shariah-compliant operations and the scarcity of trained personnel knowledgeable in Islamic principles pose significant barriers (Junaidi, 2020). However, the potential for growth in this market is substantial, with countries like Malaysia and Indonesia making concerted efforts to position themselves as leading halal tourism destinations (Marzuki et al., 2019; Trishananto et al., 2024). The integration of halal principles with sustainable economic models also presents an opportunity for the industry to appeal to environmentally conscious consumers while adhering to Islamic ethical standards (Raimi, 2025).

The halal-friendly hospitality industry is evolving with new trends and practices. For instance, the use of digital platforms to market halal attributes and the development of mobile applications to locate halal eateries and services are becoming increasingly common (Hashim et al., 2025). Moreover, the concept of Shariah-compliant hotels is expanding beyond food and accommodation to include holistic services such as halal-friendly transportation and recreational activities (Abas et al., 2017; Marzuki et al., 2019). These developments indicate a broader acceptance and integration of halal principles in the global tourism industry, paving the way for more inclusive and diverse travel experiences for Muslim tourists. In conclusion, the halal-friendly hospitality sector is poised for significant growth, driven by the increasing demand for services that align with Islamic principles. While challenges remain, the industry’s ability to adapt and innovate will be crucial in meeting the needs of Muslim travelers and capitalizing on the opportunities in this burgeoning market.

METHODOLOGY

Bibliometrics refers to the process of collecting, organizing, and analyzing bibliographic information from scientific literature (Alves et al., 2021; Assyakur & Rosa, 2022; Verbeek et al., 2002). It goes beyond basic metrics such as identifying key journals, publication dates, and prominent authors  (Wu & Wu, 2017) by employing advanced methods like document co-citation analysis. A robust literature review requires a systematic and iterative process that involves selecting appropriate keywords, retrieving relevant literature, and conducting thorough evaluations. This methodology enables the development of a well-rounded bibliography and ensures dependable findings (Fahimnia et al., 2015).

In line with this, the present study concentrated on highly cited works, as they offer valuable perspectives on the theoretical foundations of the research domain. To guarantee data reliability, SCOPUS was used as the primary database for sourcing publications (Al-Khoury et al., 2022; di Stefano et al., 2010; Khiste & Paithankar, 2017). For quality control, only peer-reviewed journal articles were included in the analysis, while materials such as books and conference proceedings were excluded (Gu et al., 2019). The dataset, derived from Elsevier’s Scopus database recognized for its extensive coverage comprises publications from the year 2004 up to December 2025 for in-depth examination.

Data Analysis

VOSviewer is an intuitive bibliometric analysis tool created by Nees Jan van Eck and Ludo Waltman at Leiden University in the Netherlands (van Eck & Waltman, 2010, 2017). It is widely recognized for its effectiveness in visualizing and exploring scientific literature, particularly through the development of network diagrams, item clustering, and density visualization. Its functionality supports analysis of co-authorship patterns, citation links, and keyword co-occurrence, offering comprehensive insights into scholarly trends. With a user-friendly interface and regular software enhancements, VOSviewer enables seamless navigation of extensive datasets. Its capabilities to compute bibliometric indicators, adapt visual outputs, and integrate data from various sources make it a preferred choice among researchers examining complex academic domains.

A defining strength of VOSviewer is its ability to convert large and complex bibliometric data into clear, visual representations such as maps and charts. Emphasizing network visualization, the software efficiently identifies and groups related items, detects patterns of keyword occurrence, and generates density-based visuals. Both beginners and experienced users benefit from its accessible interface. Ongoing development ensures that VOSviewer remains a cutting-edge tool for bibliometric exploration, offering advanced customization and analytical features. Its flexibility in handling diverse bibliometric structures including citation, co-authorship, and keyword networks establishes VOSviewer as an essential tool for scholars seeking rich and detailed research insights.

For this study, bibliometric data covering the period from 2004 to December 2025 were extracted in PlainText format from the Scopus database. These data included publication year, titles, authors, journals, citation counts, and keywords. The analysis was conducted using VOSviewer version 1.6.19. Leveraging VOS clustering and mapping algorithms, the software facilitated the construction of visual maps. Unlike the Multidimensional Scaling (MDS) technique, which it nonetheless resembles in spatial representation (van Eck & Waltman, 2010) (Appio et al., 2014). VOSviewer adopts an alternative method for mapping that places items in a low-dimensional space in a way that their distances reflect the degree of relatedness. Instead of using similarity measures like cosine or Jaccard indices, VOSviewer employs the association strength (ASij), calculated as follows (Van Eck & Waltman, 2007):

This formula represents the ratio of the actual number of co-occurrences between items i and j to the expected number of co-occurrences assuming statistical independence. This approach allows for a more accurate and meaningful normalization of co-occurrence data (Van Eck & Waltman, 2007).

\[
\tilde{A}_{ij} = \frac{C_{ij}}{w_i \, w_j}
\]

Data Search Strategy

For this bibliometric analysis on Halal-Friendly Hospitality Services, data was extracted from the Scopus database using a refined advanced search strategy to ensure the relevance and specificity of the dataset. The search string applied was: TITLE (“Halal tourism” OR “Islamic tourism” OR “Muslim-friendly tourism” OR “Halal travel” OR “Shariah-compliant tourism”) as refer Table 1. This query focused exclusively on titles, which is a deliberate approach to capture only those documents where halal-related tourism themes are the central focus of the study. By targeting these specific and synonymous terms, the search ensured comprehensive coverage of the core concepts underpinning halal hospitality research.

The final search yielded 620 documents, forming the foundation for the bibliometric analysis. This dataset reflects the scope of scholarly work spanning multiple disciplines, such as business, social sciences, tourism studies, and religious studies. The use of title-only filtering may exclude peripheral studies where halal tourism is a secondary theme; however, it enhances precision by prioritizing works with primary relevance. This focused strategy supports the reliability and validity of the bibliometric indicators analyzed later in the study such as publication trends, keyword co-occurrence, author collaboration, and geographical contributions—ensuring that the analysis remains concentrated on the key developments within halal-friendly hospitality services.

These insights reveal both established leaders and emerging contributors in the halal hospitality research landscape, presenting opportunities for enhanced international collaboration and capacity building.

CONCLUSION

The primary objective of this study was to map the scholarly landscape of halal-friendly hospitality services through a bibliometric analysis, focusing on industry practices and academic developments from 2004 to 2024. By examining key trends in publication volume, influential authors, collaborative networks, dominant keywords, and subject areas, this study aimed to provide a consolidated overview of research activity in this emerging field. The analysis identified a consistent increase in research output over the past decade, with Indonesia and Malaysia leading in terms of publication volume and influence. Business, management, and social sciences emerged as the dominant subject areas, reflecting a strong focus on consumer behavior, service quality, and policy integration in halal tourism. Key research themes included Muslim tourist satisfaction, Shariah-compliant service standards, destination branding, and ethical tourism practices. Despite growing scholarly attention, the study revealed limited cross-country collaboration, highlighting the need for broader international research networks.

This study contributes to the academic field by offering a structured synthesis of existing literature and visualizing knowledge clusters using bibliometric tools. The findings expand the understanding of how halal tourism is conceptualized, implemented, and studied across regions. Moreover, the research demonstrates the growing relevance of digital tools and interdisciplinary approaches, including artificial intelligence, sentiment analysis, and structural modelling, in advancing halal hospitality research. The insights obtained have practical implications for policymakers, tourism operators, and certification bodies seeking to enhance Muslim-friendly travel experiences. Understanding dominant themes and gaps can help guide strategic decisions, product development, and standard-setting efforts to meet the growing demand for Islamic-compliant hospitality services globally.

Nonetheless, the study is limited by its reliance on a single database (Scopus) and its focus on title-based keyword selection, which may omit peripheral yet relevant studies. This study also has offered a comprehensive bibliometric mapping of Halal-friendly hospitality services, highlighting the evolution of scholarly output, influential contributors, and dominant thematic areas. While the research landscape is rapidly maturing, it remains concentrated within specific disciplinary silos such as business and management. The lack of interdisciplinary integration and limited global collaboration, particularly with researchers from non-Muslim-majority countries, presents a critical gap in the advancement of the field. Malaysia and Indonesia continue to lead, yet their strategic influence could be amplified through diversified engagement, technology integration, and policy-aligned innovations.

Future research on Halal-friendly hospitality should move beyond its current disciplinary boundaries and embrace a more integrative approach. Scholars are encouraged to explore intersections with information technology, environmental sustainability, and consumer psychology. By incorporating tools such as digital service platforms, sentiment analysis, and behavioural models, researchers can provide richer, more applicable insights into Muslim tourist experiences. Additionally, the development of robust conceptual frameworks that address the links between Halal certification, customer trust, service quality, and destination loyalty is necessary to enhance theoretical grounding. These models can then be tested through rigorous empirical methods to ensure their validity across diverse settings. Moreover, the expansion of international collaboration is crucial for the field’s growth. Joint research projects with institutions outside the Muslim world, particularly in Europe, East Asia, and Africa, would bring in comparative perspectives and foster greater academic visibility. These efforts should align with global policy initiatives such as the Global Muslim Travel Index (GMTI) and the United Nations Sustainable Development Goals (SDGs), which provide valuable benchmarks for ethical and inclusive tourism. By aligning research agendas with both national tourism policies and international standards, Halal hospitality scholarship can make a more significant impact on global tourism development and policy implementation.
