Ahmad bin Muhammad bin Hanbal Ash-Shaybani (Arabic: أبو عبد الله أحمد بن محمد بن حنبل الشيباني; 780–855 CE/164–241 AH) was a theologian, jurist and hadith scholar. One of the four Imams of Fiqh and the founder of a juristic school now know as Madhhab Al-Hanbaliya (The Hanbal Juristic School). 
Born in Baghdad in the month of Rabi al-Awwal 164 AH; died, Friday the 12th of Rabi al-Awwal 241 AH.
Ibn Hanbal studied Fiqh and Islamic disciplines in Baghdad, then travelled to Ash-SHam and Hijaz for further study.
He refused to accept the Mu’tazila innovated view (Bid’a) that the Qur’an was created which resulted in his persecution during the rule of Al-Mamun ibn Harun Ar-Rashid.
His most recognized work, Ahadith collection of 28-29 thousand hadith known as Musnad Ahmad ibn Hanbal. Legends say he memorized a million hadith.
