Although the integration of digital technology in language education has received increasing scholarly attention, comprehensive research on Islamic online technology in Arabic language learning remains limited, particularly in madrasah contexts where technological innovation must align with Islamic educational values. This study aims to explore the forms of technological integration in Arabic language instruction, examine teachers’ and students’ responses to digital innovation, and analyze the contribution of Islamic online technology to improving Arabic language learning while preserving Islamic values at MA Darul Muhajirin Praya Lombok. Employing a qualitative descriptive case study design, the study involved 28 participants, with data collected through semi-structured interviews, classroom observations, and document analysis and analyzed using thematic analysis. The findings indicate that Islamic online technology was systematically integrated through digital learning platforms, blended online instructional strategies, and interactive multimedia tools. Teachers and students reported positive perceptions of usefulness, ease of use, and increased learning engagement, although challenges related to internet connectivity and digital access remained evident. The findings further show that Islamic online technology improved students’ Arabic language skills, expanded learning accessibility and flexibility, and supported the preservation of Islamic educational values through supervised digital content and value-oriented instructional practices. The study concludes that Islamic online technology functions as both an effective pedagogical innovation and a strategic mechanism for sustaining Islamic educational identity in Arabic language learning. These findings contribute to the literature on digital pedagogy and Islamic education and offer a contextual model for digital transformation in madrasah-based Arabic language instruction. Future research should conduct multi-site and longitudinal investigations to examine the sustainability of broader implementation.
