Digital transformation has significantly impacted Islamic da'wah, opening up opportunities to expand the reach and impact of religious teachings through digital platforms and social media. This research examines the role of information technology in expanding da'wah, its use in increasing interaction and involvement of mad'u, and the challenges faced in maintaining the authenticity and quality of da'wah messages in the digital world. Through a literature review approach, this study collects and analyzes relevant literature regarding the use of technology in da'wah, as well as its impacts and challenges. The results show that digital technologies like YouTube, Instagram, and Islamic-specific apps have enabled preachers to reach a wider audience, including urban and global communities. Nonetheless, the rapid and unverified dissemination of information can weaken religious authorities and lead to misinformation. In addition, technology increases the interaction and involvement of mad'u and introduces challenges in maintaining the authenticity of da'wah messages. Developing digital literacy and an ethical approach to disseminating da'wah is essential to overcome these challenges. Overall, although digital da'wah presents great opportunities, there is a need for supervision and cooperation between technology, education, and regulations to ensure the quality and authenticity of the da'wah messages conveyed.
