الموفق ابن الخلال

Abu al-Hajjaj Yusuf ibn Muhammad al-Muwaffaq, known as Ibn al-Khallal, head of the chancery in Egypt in the state of al-Hafiz al-Ubaydi and after him. Imad al-Din al-Isfahani described him as "the overseer of Egypt, the man who oversaw it, and the gatherer of its glories". He had great power in epistolary writing ².

al-Qadi al-Fadil relates that when he came to the chancery of correspondence as a boy, he asked him what he had prepared for the art of writing. He answered that he had nothing but the memorising of the Qur'an and the book al-Hamasa. Ibn al-Khallal said that this was sufficient eloquence. Ibn Khallikan doubted the report, because al-Qadi al-Fadil did not enter Egypt until the days of al-Zafir ².

He lived a long time, and in the last part of his life he was harmed and kept to his house. He died in Jumada al-Akhira of the year 566 AH ³.
