النهاية في غريب الحديث (Al-Nihayah fi Gharib al-Hadith)

Compiled by Ibn al-Athir, this monumental lexicon remains one of the foundational references in understanding obscure expressions in hadith and early Islamic reports. It systematically clarifies uncommon vocabulary, drawing upon earlier linguistic authorities, and serves as a crucial tool for accurate interpretation of prophetic language.
