Ishaq was a minor member of the Abbasid dynasty, being a nephew of the caliphs al-Saffah (r. 750–754) and al-Mansur (r. 754–775). He is mentioned as being in Iraq in 817, when he played a small role in supporting the anti-caliph Ibrahim ibn al-Mahdi.[1]

In 824 Ishaq was appointed governor of the Yemen for the caliph al-Ma'mun (r. 813–833), and he arrived in Sana'a at the end of that year. His governorship of the province proved to be extremely tumultuous, and he was soon accused of treating the Yemenis in a harsh manner. Affairs in the province eventually became so disorderly that al-Ma'mun decided to dismiss Ishaq, and Muhammad ibn Nafi' was appointed as governor in his place.[2]

In 830, Ishaq was selected to lead the pilgrimage,[3] and around the same time, he was re-invested with the governorship of the Yemen in order to fill the political vacuum that had prevailed in the region following the killing of Abu al-Razi Muhammad ibn 'Abd al-Hamid. Ishaq accordingly made his way to the province and established himself in Sana'a, but took no action against Abu al-Razi's killer, the rebel Ibrahim ibn Abi Ja'far al-Manakhi, who was allowed to maintain his position in the southern highlands. Ishaq's second governorship continued until he either died or was dismissed, and he was succeeded by Abdallah ibn Ubaydallah ibn al-Abbas.[4]
