Imam Ahmad ibn Hanbal أبو عبد الله أحمد بن محمد بن حنبل الشيباني

Imam Ahmad b. Muhammad b. Hanbal al-Shaybani rahimahullah (164-241 AH / 780-855 CE) was the founder of the Hanbali school of fiqh and one of the supreme hadith masters of third-century AH Baghdad. Born in Baghdad to a family of Arab tribal lineage (Shayban), he devoted his life to the collection and criticism of prophetic narrations, traveling extensively to hear hadith from the major scholars of his time. He is best known for two legacies: his founding of the Hanbali legal school, one of the four canonical Sunni madhabs, and his unwavering stance during the mihna - the Mutazili inquisition, backed by three successive Abbasid caliphs, that attempted to force scholars to declare the Qur'an created. Imam Ahmad endured imprisonment and severe physical punishment but refused to recant, making him the enduring symbol of Sunni doctrinal steadfastness. His Musnad, containing approximately 27,000 to 30,000 narrations organized by the chain of each companion, is the largest of the canonical Sunni hadith collections and a foundational reference for identifying which companion transmitted which report.
