Al-Mufawwad

Ja'far ibn al-Mu'tamid, better known by his regnal name of al-Mufawwad ila-llah (Arabic: المفوض إلى الله‎‎, "Agent of God"), was a son of the Abbasid caliph al-Mu'tamid and heir-apparent of the Caliphate from 875 until his sidelining by his cousin al-Mu'tadid in 891.

Ja'far ibn al-Mu'tamid is first mentioned on al-Tabari's history in 872. On 20 July 875, al-Mu'tamid formally arranged for the governance of the state and his succession: Ja'far, given the honorific name al-Mufawwad ila-llah, was named heir-apparent and assigned the western half of the Caliphate, while al-Mu'tamid's brother, Abu Ahmad, known as al-Muwaffaq, received the eastern provinces and was named second heir, except for the event that the Caliph died while al-Mufawwad was still a minor. Al-Mufawwad was thus responsible for Ifriqiya, Egypt, Syria, the Jazira and Mosul, Armenia, Mihrajanqadhaq and Hulwan, with Musa ibn Bugha as his deputy. Nevertheless, it was al-Muwaffaq who held the actual power in the state, and this division of authority seems to have been mostly on paper; according to Hugh N. Kennedy, "it does not seem that al-Mufawwad exercised any real authority".

When al-Mu'tamid left Samarra in March 876 to lead the army south to confront the Saffarid army in what would be the Battle of Dayr al-'Aqul, al-Mufawwad was left behind to supervise the capital, with the aid of Muhammad al-Muwallad. In 882/3, when al-Mufawwaq and the powerful autonomous governor of Egypt, Ibn Tulun, fell out and open conflict broke out among them, al-Muwaffad was obliged to publicly curse and deprive his nominal subordinate Ibn Tulun of his offices, which went to the governor of Mosul, Ishaq ibn Kundaj. In the event, however, Ibn Tulun prevailed over the Abbasid attacks and remained in charge of Egypt, as did his son Khumarawayh after him.
