Al-Mustaḍīʾ died on 2 Dhū'l-Qaʿda — nine years and seven months of a caliphate remembered for general security, generosity, and a clemency the people had never seen; «he lived praised and died happy». Ẓahīr al-Dīn Ibn al-ʿAṭṭār secured the bayʿa for his son al-Nāṣir li-Dīn Allāh — opening the longest caliphate in Abbasid history 1.

Summary

The caliph al-Mustadi bi-Amr Allah died on the second of Dhu al-Qaʿda. His caliphate had lasted about nine years and seven months. He was just, of good conduct, generous and forbearing; according to Ibn al-Athir he lived a praiseworthy life and died a fortunate death. Zahir al-Din ibn al-Attar then took the oath of allegiance for his son al-Nasir li-Din Allah, and the longest Abbasid caliphate was thereby begun 2.
