Ahmad ibn Hanbal (Arabic: أحمد ابن حنبل, romanized: Aḥmad ibn Ḥanbal; (164-241 AH; 780 – 855 CE) was an Arab jurist and founder of the Hanbali school who is widely recognized as the scholar who memorized the most Hadiths in Islamic history. One of the most venerated Islamic intellectual figures, ibn Hanbal is notable for his unmatched memorization of over one million prophetic narrations, an unprecedented number that has never been claimed by any other muhaddith. Ibn Hanbal also compiled the largest hadith collection, al-Musnad, which has continued to exercise considerable influence on the field of hadith studies up to the present time, shaping the methodological framework later employed in both Sahih Bukhari and Sahih Muslim. Imam al-Dhahabi described him as “the true Imam, the proof of the religion, the master of hadith, and the leader of the Sunnah”. Imam Ali ibn al-Madini said: “Truly, Allah supported this religion through two men, to whom there is no third: Abu Bakr during the Ridda Wars, and Ahmad ibn Hanbal during the Mihna”.
Having studied jurisprudence and hadith under many teachers during his youth, Ibn Hanbal became famous in his later life for the crucial role he played in the Mihna instituted by the Abbasid caliph al-Ma'mun toward the end of his reign, in which the ruler gave official state support to the Mu'tazili doctrine of the Quran being created, a view that contradicted the orthodox position of the Quran being the eternal, uncreated word of God. Living in poverty throughout his lifetime working as a baker, and suffering physical persecution under the caliphs for his unflinching adherence to the traditional doctrine, Ibn Hanbal's fortitude in this particular event only bolstered his "resounding reputation" in the annals of Sunni history.
