Research on Qur'anic rhetoric has largely focused on structural aspects, while its role in fostering social solidarity in contemporary Muslim societies remains underexplored. This study identifies the types of muhassināt al-ma'nawiyyah in Surah Al-Insān verses 1-15, analyzes their rhetorical function, and examines their relevance for social solidarity. The method is qualitative content analysis of the verse text, supported by secondary data from balāghah literature, tafsir, and prior studies. Findings show that three devices, al-ṭibāq, murā'āt al-naẓīr, and al-tafrīq, work together to construct a discourse of solidarity. Sociologically, al-ṭibāq reinforces social boundaries by contrasting gratitude with ingratitude (kufr) and safety with duress; murā'āt al-naẓīr typifies vulnerable groups, namely the poor, orphans, and captives, and rejects symbolic transactions in charity; al-tafrīq plays the most important role by distinguishing al-abrār from al-kāfirīn, vulnerabilities that require different responses, and pressure from glory. Practically, verses containing al-tafrīq (QS. Al-Insān: 4-5, 8-9, 10-11, 13-15) are recommended as teaching material for religious educators, Islamic boarding schools, and mosque-based programs. Theoretically, this research offers a functional analysis of muhassināt al-ma'nawiyyah bridging balāghah and sociology.
