Imam Ahmed ibn Hanbal (780 - 855) was an important Muslim scholar and theologian. He is considered the founder of the Hanbali school of fiqh. His full name was Ahmed bin Muhammad Hanbal.

Imam Hanbal was born in Central Asia to Arab parents in 780. After the death of his father, he would move to Iraq and study extensively in Baghdad, and later used his travels to further his education. He was chiefly interested in acquiring knowledge of the hadith and travelled extensively through Iraq, Syria, and Arabia studying religion and collecting traditions of Muhammad.

His travels lasted several years. Upon returning home, he studied under Imam Shafi on Islamlic law. Imam Hambal was very devoted to traditional views and was opposed to innovations in Islamic law.

The strength of his views was tested when under the caliphs al-Ma'mun and al-Mu'tasim. During their reign an 'inquisition court' was created to deal with people who would not profess certain doctrines that the Abbasid caliphs thought were correct. These doctrines were from the Mutazilite school of though, and held that the Qur'an was created and not eternal. Imam ibn Hanbal, suffered as a result when he was arrested and brought in chains before the court. But he patiently submitted to corporal punishment and imprisonment and resolutely refused to deviate from his beliefs.

Under the rule of Al-Mutawakkil however, the policy of the government changed and Imam ibn Hanbal's trials came to an end. From then onwards the Imam was accorded honor befitting his great knowledge and on several occasions he was invited to the court and granted a generous pension.

Among the works of Imam ibn Hanbal is the great encyclopaedia of Traditions called Musnad, compiled by his son from his lectures and amplified by supplements - containing over twenty eight thousand traditions. His other works include Kitab-us-Salaat, on the Discipline of Prayer and Kitab-us-Sunnah, on the Traditions of the Prophet.

Imam ibn Hanbal's fame spread far and wide. His learning, piety and unswerving faithfulness to traditions gathered a host of disciples and admirers around him. His teachings plus his books would lead his disciples to form the Hanbali school of jurisprudence.

He would die in Baghdad in the year 855, over 800,000 people would attend his funeral.
