Muhammad Ibn al-Athir al-Jazari rahimahullah (544-606 AH / 1149-1210 CE) was a classical Muslim scholar who excelled in hadith studies, history, and Arabic language sciences. He was born in Jazira (northern Iraq/Syria region) and served in administrative roles under the Zangid rulers while dedicating himself to scholarship.
