Controversies in Islamic Religious Education (IRE) in the modern era have often centered on efforts to integrate normative Islamic values with the complex influence of modernity. This discourse includes divergent views on the interpretation of sacred texts and their implications for a more inclusive or exclusive understanding of religion. Controversies also arise regarding the appropriate boundaries for accommodating local wisdom to ensure it does not conflict with the principles of Islamic teachings [12] . These debates reflect the ongoing tension between preserving the essence of Islamic teachings and adapting them to meet the demands of an ever-changing sociocultural context. Thus, the controversy surrounding cultural integration in IRE is a critical component in formulating religious education approaches that respond to the challenges of the time [13] .

Proponents of cultural integration in IRE have argued that this approach aligns with Islam's universal principle of rahmatan lil alamin (mercy for all creation), allowing Islamic teachings to engage positively with diverse cultural contexts [14] . This view is supported by the understanding that accommodating local wisdom can enrich religious practice and make Islamic values more accessible and comprehensible to a plural society [15] . Studies have shown that culturally based IRE can improve students' comprehension of religious values through familiar cultural media [16] . Culturally grounded approaches have also been viewed as crucial in fostering constructive dialogue across religious and cultural groups, reflecting the broad and inclusive spirit of Islam [17] .

Culturally-based IRE has demonstrated various practical benefits in improving students' understanding and internalization of Islamic teachings [18] . Case studies have revealed that the use of familiar cultural media, such as local arts and traditions, can make religious values feel more relevant and engaging to learners [19] . Research also indicates that cultural integration in IRE improves students' comprehension of Islamic values more profoundly and contextually [20] . Furthermore, the incorporation of local wisdom in Islamic education is seen as a vital step in building institutions that are deeply rooted in the sociocultural fabric of Indonesian society [21] .

Some ulama and education experts have expressed caution regarding cultural integration in IRE due to concerns about the potential compromise of the purity of Islamic teachings as derived from the Qur'an and Sunnah [22] . They emphasize the need to preserve the authenticity of Islamic values in the face of modern and global influences, which may introduce cultural elements that are not in alignment with religious principles [23] . The controversy surrounding scriptural interpretation is also a point of concern, with critics warning that cultural integration might open the door to excessively liberal or deviant interpretations that are apart from the views of the salaf (pious predecessors) [24] . Therefore, this perspective advocates for a more conservative approach to religious education, aiming to safeguard the foundational doctrines of Islam from external cultural contamination [25] .

The more conservative perspective also highlights the necessity of clearly defined boundaries in cultural integration to prevent potential risks to the correct understanding and practice of Islamic teachings [26] . Concerns have been raised about the possibility of introducing cultural values that contradict core Islamic beliefs, which could lead to deviant interpretations or even the erosion of Islamic authenticity [27] . The risk of increasing intolerance may also arise if excessive emphasis is placed on local culture without a balanced understanding of the diversity within Islam itself [28] . Thus, caution is necessary when selecting cultural elements for integration, ensuring they remain aligned with the firm framework of Islamic teachings.

In the words of Allah SWT, Surah Al-Hujurat [49]: 13: "O mankind! We created you all from a male and a female, and made you into nations and tribes so that you may know one another. Verily, the most honourable among you in the sight of Allah is the most righteous. Surely Allah is All-Knowing, All-Aware. (Surah Al-Hujurat [49]:13). This verse emphasizes that cultural and ethnic diversity is a divine blessing intended to foster mutual understanding and harmony. In the context of IRE, the controversy surrounding cultural integration becomes a call for constructive dialogue grounded in wisdom and awareness that true honor before Allah lies in righteousness beyond cultural differences. Hence, integrating cultural values that are aligned with Islamic principles becomes a tangible manifestation of this verse within the educational context, shaping a generation that is faithful, tolerant, and appreciative of diversity.

There are differing views among ulama regarding the boundaries of cultural integration in religious education. Concerns have been raised over the potential mixing of Islamic teachings with local traditions that might not align with core religious principles. The table below outlines these perspectives in detail.

The debate on cultural integration in Islamic Religious Education (IRE) reveals two distinct and often opposing schools of thought. The first group supports integration, arguing that this approach can make Islamic teachings more relevant to students' daily lives. In turn, this relevance is expected to strengthen their identity as Muslims with distinct cultural roots. They see culture as an effective bridge for conveying religious values in a way that is easier for the younger generation to understand and internalize. In contrast, the more cautious-or opposing-group expresses concern over the potential blending of Islamic teachings with local cultural practices that may not align with the religion's fundamental principles. This group emphasizes the importance of preserving the purity and authenticity of Islam by adhering strictly to its primary sources without allowing external cultural influences to distort the core message [31] .

A clear pattern that emerges from this debate is the polarization of views among ulama and education scholars. On one side, there is a tendency to view culture as a powerful medium for bringing Islamic teachings closer to the younger generation, using symbols and practices familiar to them. This approach emphasizes that Islam is a flexible religion capable of integrating with various civilizations without losing its essence. On the other side, there is a more conservative tendency, concerned that any form of acculturation could erode the core values of Islamic teachings and open the door to practices lacking strong shar'i foundations. This contrast underscores the need to find a middle ground or develop an integration model that accommodates both perspectives, ensuring that Islamic religious education remains relevant and engaging for students without compromising its fundamental principles [32] .

The methods of IRE have evolved from traditional to more modern forms, with global trends increasingly linking education to students’ cultural contexts. In response, digital technology and the arts have emerged as popular tools to support this shift. The table below compares the transformation of IRE methods from traditional to digital and culturally based forms:

The data in the table illustrate a significant transformation in the landscape of Islamic Religious Education (IRE) teaching methods, shifting from traditional approaches toward integration with digital technology and local cultural wisdom. Traditional methods, which once dominated, relied on physical learning sources such as classical Islamic texts, printed textbooks as primary references, and teacher-delivered notes, with the teacher serving as the sole authority in delivering knowledge. Learning interactions under this model tended to be one-directional, with the teacher serving as the central authority and students as passive recipients. Instruction was delivered face-to-face in classrooms bound by rigid schedules [33].

Meanwhile, the wave of modernization has introduced digital methods that offer revolutionary flexibility in terms of time and space. These allow students access to a much broader spectrum of learning materials, including e-books, regularly updated online articles, engaging educational videos, and a variety of interactive websites and online platforms [34] .

A prominent pattern emerging from the evolution of IRE teaching methods is the fundamental shift from a teacher-centered approach, where the teacher serves as the primary and often sole source of knowledge, and materials are primarily text-based, toward a student-centered paradigm, which places learners at the heart of an active and independent learning process. The digital era has opened up new opportunities for more flexible learning, enabling students to study at any time and from anywhere, tailored to their pace and learning styles [35] .

Additionally, culturally based methods have emerged, emphasizing the importance of contextualizing Islamic teachings within students’ local realities. These approaches incorporate traditional wisdom, meaningful folklore, inspirational arts, and culturally significant artifacts with both historical and religious value. This trend reflects a collective effort to make IRE learning not only more engaging and effective for a generation familiar with technology and their cultural heritage but also more adaptable to contemporary developments and the diverse backgrounds of learners, with the broader aim of fostering deeper understanding and more authentic religious practices [36].

Culturally based education has been increasingly recognized as a critical solution for addressing radicalism and identity crises among younger generations. This approach aims to instill Islamic values in a manner that is relevant to students' everyday experiences. By integrating culture into IRE, learning becomes more engaging, relevant, and easier for students to comprehend, as it allows them to relate religious teachings to their everyday lives and cultural environments. Furthermore, this integration can strengthen local Islamic cultural identities and foster a sense of national pride [37]. The table below outlines how culturally-based Islamic Religious Education (IRE) can be integrated into the curriculum:

The data indicate that integrating Islamic Religious Education (IRE) with local culture is perceived as an urgent and effective strategy for countering radicalism and identity crises. This is achieved through aligning learning objectives to help students understand and practice Islamic teachings within their cultural context, incorporating instructional content that reflects Islamic values in local cultures, employing teaching methods that accommodate cultural diversity, and actively engaging students in cultural experiences; utilizing learning media that highlight the richness of local Islamic culture; and conducting assessments that measure students' understanding and application of Islamic teachings in their cultural context [38] .

The emerging pattern reflects a growing effort to make Islamic education more relevant and contextually grounded for today's youth. By linking Islamic teachings with local culture, students are expected to better understand and internalize religious values, as they are delivered through media familiar to their daily lives. This integration aims to strengthen students' self-identity as Muslims who are also deeply rooted in their cultural heritage, thereby reducing the potential for identity crises and fostering a love for both religion and the homeland. Moreover, by understanding and practicing Islamic teachings within a positive cultural context, it is hoped that students will be more resilient against radical influences, which often stem from narrow and decontextualized interpretations of religion [39] .

This study examines the dynamics of culturally based Islamic Religious Education (IRE) in the modern era, exploring its associated controversies, evolving methods, and potential as a critical solution. Significant debates have persisted surrounding cultural integration in IRE, with ulama divided between those who conditionally support it to enhance relevance and those who express concern about preserving the purity of Islamic teachings. The methodology of IRE has shifted from traditional, textual, and teachercentered approaches to more flexible, digital, and culturally contextual models [40] . Cultural integration within IRE is believed to offer a viable path for addressing radicalism and identity crises by embedding Islamic values in ways that resonate with students' cultural realities, thereby reinforcing an Islamic identity anchored in local traditions [41] . These efforts require careful consideration to strike a balance between relevance and authenticity in delivering Islamic teachings across diverse cultural landscapes.

Indonesia, with its rich and diverse sociocultural landscape, requires an Islamic Religious Education (IRE) approach that can effectively embrace and respond to this reality. The discourse surrounding cultural integration in IRE reflects ongoing efforts to bridge the universal values of Islamic teachings with local wisdom and cultural practices -an effort that aligns with Indonesia's national motto, Bhinneka Tunggal Ika (Unity in Diversity). Amid the currents of globalization and contemporary economic challenges, Indonesia's Islamic education system is increasingly expected to innovate its teaching methodologies to remain relevant to younger generations, equipping them with an inclusive and moderate understanding of religion. National education policies explicitly recognize and prioritize religious education as a crucial element in shaping national character and strengthening civic values. Consequently, initiatives to integrate IRE with the richness of local culture and the potential of digital technology have become essential to developing an adaptive and responsive education system-one capable of producing Indonesian Muslim generations who are faithful, knowledgeable, and culturally grounded [42] .

This study affirms the significance of the ongoing debate on cultural integration in IRE, in line with the spirit of the Qur'an in Surah Al-Hujurat (49:13), which calls on humanity to recognize and embrace diversity across nations and tribes. The findings also align with Yosef's Scopus-indexed journal article, which emphasized the significance of multicultural self-efficacy in Islamic education in Indonesia. However, this study goes further by identifying specific polarities in the views of religious ulama concerning the limits of cultural integration, examining the evolving nature of IRE methods in the digital and culturally contextual era, and specifically exploring the potential of culturally grounded education as a solution to urgent issues of radicalism and identity crises. Thus, this study not only reinforces previous studies but also expands the understanding of the complexities of cultural integration in IRE and its urgency in today's context [43] .

The interpretation of this study's findings indicates ongoing efforts to adapt Islamic Religious Education (IRE) in Indonesia to evolving social contexts and contemporary challenges. In a multicultural society like Indonesia, there is a need for an IRE approach that balances universal religious values with local wisdom. Technological advancements and ideological threats, such as radicalism, demand teaching methods that are both relevant and contextual. As noted by Hermansyah in his article Islam and Local Culture in Indonesia, Islam is a universal religion that can adapt to local cultures. This perspective aligns with the discourse on cultural integration and the shift toward digital and culturally based learning methods, as observed in this study. Thus, the interpretation affirms that IRE in Indonesia is actively striving to remain relevant and effective in delivering Islamic teachings amidst cultural diversity and global challenges [44] .

Reflection on the results of this study highlights the need for caution and balance in the development of Islamic Religious Education (IRE) in Indonesia. While efforts to integrate culture and incorporate technology into IRE present promising opportunities to enhance educational quality and student engagement, they also pose significant challenges in terms of implementation and potential negative impacts. An article from the IKHAC Postgraduate Journal states that the development of the IRE curriculum faces complexity due to sociocultural and technological changes. This study also found ongoing debates and challenges in implementing culturally based methods to overcome radicalism and identity crises. Therefore, in-depth studies and careful strategies are necessary to implement IRE innovations effectively, ensuring they achieve their positive goals without causing unwanted dysfunction [44] .

The implications of this study suggest the need for policy actions that encourage inclusive dialogue among ulama, educators, community stakeholders, and the government to achieve a deeper understanding of cultural integration in IRE. The government and educational institutions must allocate adequate resources for teacher training to effectively and creatively implement digital and culturally based learning methods, as well as ensure equitable access to technology and supporting infrastructure for all students across various regions. Furthermore, it is necessary to design a structured program that systematically and sustainably incorporates local wisdom into the IRE curriculum to strengthen positive student identities and prevent radicalization from an early age. Close and ongoing collaboration between schools, families, and communities is also crucial in the implementation of this comprehensive action plan. Thus, the implementation of this integrated action plan is expected to improve the quality of IRE and its relevance in facing increasingly complex modern challenges [45].

Culturally-based Islamic Religious Education (IRE) represents an innovative approach that repositions religious learning within the socio-cultural realities of students. In Indonesia's diverse society, where ethnicity, language, and traditions vary widely, the relevance of IRE depends not only on its doctrinal accuracy but also on its adaptability to cultural contexts. The integration of local wisdom-such as traditional ceremonies, regional arts, folklore, and indigenous expressions-into the teaching of Islamic values can enhance students' engagement and comprehension. More importantly, this approach serves the broader mission of the Sustainable Development Goals (SDGs), especially SDG 4 (Quality Education) and SDG 16 (Peace, Justice, and Strong Institutions) [45] .

From an educational perspective, cultural integration in IRE allows for contextualized learning, enabling students to connect religious teachings with their lived experiences. This strategy fosters internalization of values rather than mere memorization of texts. It strengthens critical thinking and cultural empathy, which are essential competencies in addressing issues of religious intolerance and extremism. In terms of identity formation, this model enables students to see themselves as both devout Muslims and proud cultural citizens, bridging the often-perceived divide between tradition and modernity. However, this culturally inclusive approach is not without controversy. Some Islamic scholars warn against the risk of syncretism, where Islamic principles may be blended with cultural practices that contradict core religious doctrines. The literature identifies a clear polarization between reformist and conservative interpretations. Reformists advocate for adaptive learning models that include cultural symbols as teaching aids, while conservatives urge strict adherence to textual purity, fearing dilution of religious identity. This divide underlines the need for a framework that safeguards the authenticity of Islamic teachings while allowing flexibility in delivery methods [46] .

Recent shifts from traditional to digital education platforms have further transformed IRE. Teachers are no longer the sole knowledge providers; instead, they act as facilitators guiding students through multimedia content, interactive discussions, and culturally-rich learning materials. Digital platforms now enable access to culturally responsive resources that support diverse learning styles. When aligned with local wisdom, digital learning enhances not only content delivery but also students' emotional and spiritual connection to their heritage and faith. In supporting the SDGs, culturally-based IRE offers a transformative pathway to building peaceful, inclusive, and pluralistic societies. It encourages civic responsibility, intergroup dialogue, and resistance to radical ideologies. Therefore, cultural integration in IRE is not a superficial adaptation, but a foundational strategy to achieve educational justice and social harmony in a globalized era. With the right balance between cultural relevance and religious authenticity, IRE can contribute significantly to both national character building and international development goals [46] .
