Knowledge dissemination plays an important role in society as a means of transferring information, values, and understanding that support social development. In Islam, the dissemination of knowledge is regarded not only as an educational activity but also as a religious and social responsibility. This study aims to examine the construction of knowledge dissemination from the perspective of Hadith by exploring its fundamental concepts, methods, and ethical principles. The research employs a thematic Hadith method with a descriptive qualitative approach through library research. Data were collected from the major Hadith collections (Kutub al-Sunnah) using keywords related to knowledge, education, da‘wah, and knowledge transmission. Of the 26 Hadiths initially identified, 25 were selected for the final thematic analysis after undergoing coding and categorization processes. The findings reveal that knowledge dissemination in Hadith is constructed upon three main aspects: fundamental concepts, methods, and ethics of knowledge dissemination. Hadith views knowledge as the inheritance of the prophets that must be learned, preserved, and conveyed to others. The dissemination process is carried out through clear communication, understandable delivery, exemplary practice, and the use of analogies. Meanwhile, the ethics of knowledge dissemination emphasize trustworthiness, honesty, gentleness, sincerity, and respect for others. These findings indicate that Hadith provides a comprehensive foundation for knowledge dissemination that contributes positively to social life.
