Ahmad ibn Hanbal

Ahmad ibn Muhammad ibn Hanbal ash-Shaybani (164-241 AH / 780-855 CE) was one of the most towering figures in Islamic scholarship, the founder of the Hanbali school of jurisprudence, and one of the greatest hadith scholars of all time. Born in Baghdad, he lost his father at a young age and was raised by his mother. He began studying hadith at fifteen and traveled extensively throughout the Muslim world, studying under Imam ash-Shafii, Sufyan ibn Uyaynah, Waki ibn al-Jarrah, Yahya ibn Said al-Qattan, and many others.

Imam Ahmad's most celebrated work is the Musnad, one of the largest hadith collections ever compiled, containing approximately 28,000 narrations organized by the companion who narrated them. Beyond hadith, he was a deeply principled theologian who championed the creed of the Salaf, insisting that the Quran is the uncreated Word of Allah. This stance led to his imprisonment and torture during the Mihna, the Abbasid inquisition under Caliphs al-Mamun and al-Mutasim, who enforced the Mutazili doctrine that the Quran was created. Ahmad's refusal to capitulate, despite severe physical punishment, earned him the title Imam Ahl as-Sunnah (the Imam of the People of the Sunnah).

His legal methodology prioritized the Quran, the Sunnah, the consensus and opinions of the Companions, and sound hadith over personal reasoning (ray). The Hanbali school he founded became one of the four accepted schools of Sunni jurisprudence. He also authored works on creed, asceticism (az-Zuhd), and the virtues of the Companions. He died in Baghdad in 241 AH (855 CE), and his funeral was attended by hundreds of thousands of people. His influence on Sunni orthodoxy, hadith scholarship, and Islamic law is immeasurable.
