An inquisitive Abbasid caliph whose short reign was marked by theological controversy and a famous confrontation over the nature of the Quran.
Al-Wathiq bi'llah, 'He who trusts in God,' assumed the Abbasid caliphate in 842 during a period of fading imperial power. The vast empire was now effectively run by Turkish military commanders, but the caliph remained the symbolic heart of the Islamic world. Al-Wathiq is remembered less for political conquest and more for his deep personal involvement in a fierce theological debate of the era: whether the Quran was created or eternal. He vigorously enforced the official Mu'tazilite doctrine of the Quran's creation, presiding over a famous inquisition known as the Mihna. His direct interrogation of the traditionalist scholar Ahmad ibn Hanbal is a defining episode of his rule. A man of intellectual curiosity, he was also said to be a patron of music and scholarship. His sudden death in 847 after just five years in power left the ongoing religious and political tensions to his successor.

He was reportedly an accomplished musician and composer himself.
His regnal name, al-Wathiq bi'llah, translates to 'He who trusts in God.'
The great Arab historian al-Tabari was a young man during al-Wathiq's reign and later wrote about it.
“The ink of the scholar is more sacred than the blood of the martyr.”
