The development of digital technology has brought about major changes in the spread of da'wah and the implementation of Islamic counseling. Da'wah that used to focus on face-to-face is now transformed through social media and digital platforms, so that religious messages can reach a wider audience without time and space limitations. Digital media presents opportunities for da'i to convey da'wah with varied and interesting content, especially for the younger generation. However, challenges remain, such as the lack of direct emotional interaction and the difficulty of monitoring potentially deviant content. Meanwhile, Islamic counseling in the digital era is developing through online services, either through websites, telephones, chats, and video conferences. These services facilitate access to counselling, reduce distance barriers and social stigma, and provide flexible counseling alternatives. However, online counseling also has weaknesses, such as limitations in reading body language, network technical constraints, and counselors' skills that are not optimal in utilizing technology. Thus, Islamic da'wah and counseling in the digital era require the readiness of human resources, mastery of technology, and the application of good ethics in order to run effectively, professionally, and provide wide benefits to society.

The development of generative artificial intelligence has opened opportunities for strengthening Islamic legal learning through a digital forum that remains connected to authoritative textual references. This study aims to design and build a web-based bahtsul masail discussion system using a multi-agent AI architecture and the Retrieval-Augmented Generation (RAG) method. The proposed system simulates the deliberative roles commonly found in pesantren-based Islamic legal discussion, namely Moderator, Mubahits, Mu'aridh, and Mushahih. The research applies a Research and Development approach with the Waterfall model, covering requirement analysis, interface design, multi-agent workflow design, implementation, functional testing, and evaluation. RAG is implemented by allowing users to upload PDF documents of kitab kuning and assign the documents to particular agent roles. The uploaded texts are then used as contextual grounding so that each agent can formulate arguments, rebuttals, and final decisions based on traceable references rather than unsupported model memory. The application is implemented using HTML, CSS, and JavaScript on the front end, while the AI reasoning process is orchestrated through an API-based large language model. Functional testing shows that the system can complete five sequential stages of bahtsul masail, display role-based responses, manage uploaded references, and present discussion history. The main contribution of this study is a system design that combines pesantren deliberation procedures with AI-based retrieval support to provide an interactive learning medium for Islamic law, while emphasizing that the final authority of legal validation remains with qualified scholars
