And Carl Brockelmann (d. 1375 AH), in History of Arabic Literature, 3/129, and The Encyclopaedia of Islam, 1/72.
Two scholars compiled lists of his works: Najm Abd al-Rahmān Khalaf, in the introduction to his critical edition of Silence and the Etiquette of Speech, and Yāsīn Muhammad al-Sawwās, in the introduction to his critical edition of Gratitude to Allah, Mighty and Majestic. Both books are by Ibn Abī al-Dunyā. They documented the attribution of these works, identified the locations of their manuscripts, and recorded the publication dates of those that had appeared in print.
An anonymous author also compiled A Catalogue of the Works of Ibn Abī al-Dunyā. Dr. Salāh al-Dīn al-Munajjid published it from its manuscript held at the Zāhiriyyah Library in the journal of the Arabic Language Academy, vol. 49 (1974), pp. 579–594, as previously noted in the biographical account.
Description of the Manuscript:
The whereabouts of the manuscript of Sincerity and Intention remained unknown. Neither Brockelmann nor Sezgin mentioned it in their respective histories, nor did Khalaf in his introduction to Silence and the Etiquette of Speech, or al-Sawwās in his introduction to Gratitude to Allah, Exalted is He. Then Allah enabled me to discover it while I was consulting Ibn Urwah al-Hanbalī’s al-Kawākib al-Darārī fī Tartīb Musnad al-Imām Ahmad alā Abwāb al-Bukhārī (The Brilliant Stars: Arranging Imam Ahmad’s Musnad According to al-Bukhārī’s Chapters), in which Ibn Urwah reproduced it in full.
As its title indicates, this book contains the hadiths found in the Musnad of Imam Ahmad ibn Hanbal, arranged according to al-Bukhārī’s method of dividing his Sahīh into books and chapters.
Its author, however, had another purpose in mind: to supplement the hadiths with explanations and biographical notices on their narrators, all quoted verbatim from the works of the great hadith masters and leading Hanbalī scholars.
