Al-Mundhirī (1) said: A group of our colleagues heard ḥadith from him; he committed a great deal to writing, and his calligraphy was of outstanding quality. He held the Dīwān al-Naẓar (the Supervisory Bureau) in the Egyptian administration, moved through a succession of appointments, and lived for eighty-nine years.
Al-Muwaffaq ʿAbd al-Laṭīf said: He was brown-skinned, tall, slight of build, refined, and skilled in epistolary style. He was master of the bureau, and the celebrated jurist al-Qāḍī al-Fāḍil was among those who frequented his door, praised him, and boasted of having gained access to him. When the Ṣalāḥid regime assumed power, al-Fāḍil said, “This man enjoys great standing; he ought to be granted a stipend sufficient for his needs and allowed to remain in his home.” So it was done.
Afterwards he set out for Yemen, where he served as vizier and corresponded with Baghdad; there he was held in high honor and esteem. When I later reached Egypt I found Ibn Bunān in dire straits, burdened by a heavy debt that led the governor to confine him in the congregational mosque. He used to disparage al-Qāḍī al-Fāḍil and regarded him with the same old eye (2); consequently al-Fāḍil fell short in assisting him.
The debt was owed to a foreigner. The creditor climbed up to him on the roof of the mosque, insulted him, seized his beard, and struck him. Ibn Bunān fled, threw himself from the roof, was shattered, and was carried to his house, where he died a few days later. Al-Fāḍil sent fifteen dinars with his son for the shrouding and funeral expenses, and three days after that al-Fāḍil himself died suddenly.
Ibn Bunān passed away on the third of Rabīʿ al-Ākhir in the year 596 AH.
