The phenomenon of social sins such as ghībah (backbiting), tajassus (spying to expose faults), and sūʾ al-ẓann (negative suspicion) has become increasingly prevalent in modern society, especially in the era of Society 5.0 characterized by the merging of digital connectivity and social life. This thesis explores these issues through Nouman Ali Khan’s interpretation of Qur’an Surah al-Ḥujurāt (49:12). The research is guided by the questions: how does Nouman Ali Khan interpret al-Ḥujurāt 49:12 concerning the prohibition of social sins? and how is his interpretation relevant in the context of Society 5.0? In line with these questions, this study aims to identify the prohibitions of social sins in Qur’an Surah al-Ḥujurāt (49:12) and to analyze the relevance of Nouman Ali Khan’s interpretation as an ethical guide for digital-age society. The research employs a qualitative model using the library research method. The primary data sources are Nouman Ali Khan’s lectures on the Bayyinah YouTube channel, particularly two videos from the series Striking Examples 2.0, episodes 24 and 25. The collected data is analyzed using content analysis. This research aligns its findings with the guiding questions: first, Nouman Ali Khan’s interpretation of al-Ḥujurāt 49:12 reveals a threefold prohibition—against sūʾ al-ẓann, tajassus, and ghībah—framing suspicion, secretive fault-finding, and backbiting as a sequential threat to social trust; and second, in the Society 5.0 era of seamless digital connectivity, these prohibitions translate into practical norms—verify before sharing, honor privacy boundaries, and refrain from dehumanizing speech—thereby providing an ethical blueprint to curb hate speech, doxing, rumor-spreading, and cancel culture in modern online communities.
