Mihna

Al-Ma'mun (r. 813-833 CE) was the seventh Abbasid caliph and one of the most intellectually accomplished rulers in Islamic history. His reign marked the peak of the translation movement and the flourishing of the House of Wisdom in Baghdad, making him a central figure in the Islamic Golden Age.

Ahmad ibn Hanbal (780–855 CE) founded the Hanbali school of jurisprudence and compiled the Musnad, one of the largest hadith collections. His refusal to affirm the doctrine of the created Quran during the Mihna made him the symbol of scholarly independence from political power.

The Mu'tazilite school was a major rationalist theological movement of the Abbasid era that placed reason at the center of Islamic thought, shaping centuries of debate over divine justice, free will, and the nature of the Quran.

The Mihna (833–848 CE) was a fifteen-year inquisition begun by Caliph al-Ma'mun to enforce the Mu'tazilite doctrine that the Quran was created. Its failure, symbolized by Ahmad ibn Hanbal's resistance, established the independence of religious scholarship from political authority.
