Why this is in the register
The Arabic text was edited at the Franciscan Centre in Cairo (Majmūʿ uṣūl al-dīn wa-masmūʿ maḥṣūl al-yaqīn, Cairo 1998-1999) and translated into Italian, not English: Summa dei principi della religione (Cairo, 1998-2002) — HOLLIS language field 'ita': https://hollis.harvard.edu/discovery/search?query=any,contains,Majmu%20Usul%20al-Din%20Mutaman&tab=Everything&search_scope=MyInst_and_CI&vid=01HVD_INST:HVD2&offset=0 . The same query returns Wadi Abullif's Arabic/Italian study of the Summa and an English doctoral-style study by Peter Doghramji (2017) which is a study, not a translation. No English translation appears in HOLLIS, in the CCE entry on the author (CE, 'Muʾtaman Abu Ishaq Ibrahim Ibn Al-ʿAssal', https://ccdl.claremont.edu/digital/collection/cce/id/1423), or in the Brill/Gorgias Copto-Arabic lists.
The most systematic of the Copto-Arabic summae — 69 chapters using Islamic kalām and falsafa to construct a Coptic Orthodox theology, and the work in which Ibn al-Rashid's Tiryāq is quoted. The Italian translation (translator not verified in the catalogue record, therefore left blank) makes it accessible to Italian readers only; there is no English version of a text that scholars routinely compare with Latin scholastic summae.
No open electronic text was verified for this work. The Greek/Coptic/Geʿez may exist only in a print or subscription edition (Migne, CSCO, TLG, CMCL).
Scanned witnesses
Scan search: restricted scan — 4 candidate(s). Found through the HMML full metadata dump (https://www.vhmml.org/datasets/vhmml_rr_fulldata.zip, 48.4 MB zip -> 757,760,065 B JSON, Last-Modified 2026-11-09) grepped for the uniform title 'Majmu' usul al-din wa-masmu' mahsul al-yaqin' (6 hits = 4 distinct records). All four are image-only manuscript witnesses; HMML holds no transcription, so an English translation must be made from the images. No scanned print of the Cairo 1998-99 Arabic edition or the Italian Summa was located: IA advancedsearch title:(Ibn al-Assal) and title:(Mu'taman) return 0, and IA full-text/metadata searches for the Arabic title return unrelated modern theology. The Vatican's DigiVatLib title search now answers 403 from this host, so Vat.ar. holdings could not be checked by title.
