Majd ad-Din ibn al-Athir

Majd ad-Din al-Mubarak ibn Muhammad ibn al-Athir al-Jazari (544-606 AH / 1150-1210 CE) was a distinguished scholar, linguist, and hadith specialist from Jazirat ibn Umar (in present-day southeastern Turkey). He was the eldest of three famous scholarly brothers: Majd ad-Din (the linguist), Izz ad-Din (the historian), and Diya ad-Din (the literary critic). He studied under scholars in Mosul and Baghdad and served in the administration of the Zangid rulers.

Majd ad-Din's most important work is an-Nihayah fi Gharib al-Hadith wal-Athar (The End in Rare Hadith and Traditions Terms), a comprehensive dictionary explaining obscure and rare Arabic words found in hadith and the statements of the Companions and Successors. Building upon earlier works by Abu Ubayd al-Qasim ibn Sallam and al-Zamakhshari, an-Nihayah became the definitive reference for understanding difficult vocabulary in hadith literature. He also authored Jami al-Usul fi Ahadith ar-Rasul, a compilation that merged the six canonical hadith collections into a single work organized by topic, making it easier to locate and cross-reference narrations.

Majd ad-Din suffered a stroke later in life that left him partially paralyzed, but he continued his scholarly work with the help of scribes. He died in Mosul in 606 AH (1210 CE). His an-Nihayah remains the standard reference for understanding rare vocabulary in hadith, and his Jami al-Usul is valued as a practical tool for accessing the canonical collections.
