[Colour scanned images of the textblock and covers.]

Single work: Arabic. Date:

undated; c. 12^th/18^th c.

Or.:

unknown; copied by Abū Aḥmad Shams al-Dīn Muḥammad, known as al-Ashraf, from an exemplar dated 778/1376-7, which in turn was copied from the autograph dated 5 Shawwāl 644/13 February 1247 (p. 269). The scribe further quotes a note in the exemplar stating that al-Ṭūsī confirmed on 24 Jumādā l-ūlā 661/5 April 1263 that a copy by the hand of Imām al-Kabīr al-Fāḍil al-Walad Shams al-Milla wa-l-Dīn Sayyid al-ʿUlamāʾ wa-l-Aʾimma ʿAbd al-Kāfī had been read to him by the scribe (p. 269). MS Istanbul, Millet, Feyzullah Efendi 1361, copied in 778/1376-7 and likely the exemplar of the present manuscript, and MS Patna, Khuda Bakhsh, HL 3477 likewise derive from the copy by ʿAbd al-Kāfī.

Prov.:

Old shelfmark (?): 1263 1/2 (sticker on front cover) or 1263 1/2 jadīd (front flyleaf). The codex was part of the private collection of Shaykh Ḥasan b. Muḥammad b. ʿAlī al-Thānī (b. 1960) and was transferred to the Qaṭar National Library in 2009 as part of its Heritage Collection (HC).

Cod.: paper, V+269+V^a pp. (paginated with Persian variants of Hindu-Arabic numerals in pencil at the top center, with 263 to 267 repeated after p. 267 and here referred to as 263^bis to 267^bis; catchwords). A single black nastaʿlīq hand with minor tendency to naskh; mostly dotted ductus with few vowel marks and hamzas, rare shaddas. Book titles mostly overlined; blank spaces reserved for book numbers II, V, VII and IX–XIII with most supplied in the margins; section titles with dark red overlines, preceded by abjad numerals. Abjad numerals and Persian variants of Hindu-Arabic numerals overlined. Diagrams with dark red lines and black geometrical points or sometimes vice versa. Tables with dark red lines. Codex in very good condition; brownish spot in the upper third of the fore-edge and margins, probably caused by fire or water; upper outer part of pp. V–1 and lower outer part of pp. 296–I^a torn and restored. Dimensions: not given; 18 lines per page. Cardboard covers with marbled paper and dark-green, dark-brown and purple cloth; damage on the back cover in the form of two parallel horizontal lines, likely caused by attached strings.
