Among the numerous kalām works by the Imāmī al-Sharīf al-Murtaḍā (d. 436/1044), his Kitāb al-Mulakhkhaṣ and his Kitāb al-Dhakhīra are his most comprehensive writings in this discipline. The relation between the two works and their respective transmission is discussed. The Kitāb al-Dhakhīra is also incompletely preserved in the transcription of the Karaite scholar ʿĀlī b. Sulaymān al-Maqdisī, completed in Fusṭāṭ in Rajab 472/December 1079-January 1080 (National Library of Russia, St. Petersburg, Ms. RNL Arab. 111). The codex is described in detail, and its implications for our knowledge of the transmission of the work are analyzed.
See, e.g., Dhakhīra, p. 127,where a chapter is opened with a reference to an earlier discussion about will which is not preserved in the edited text (qad maḍā fī hādhā l-kitāb anna l-irāda tataʿallaqu bi-murādihā ʿalā jihat al-ḥudūth …).
