Place in the story

    Sunni (documented)

    Roles are dated and sourced; the museum describes the act and attributes the judgement.

    From Denia to Marrakech

    Abu Jafar Ahmad ibn Ibrahim ibn Ali ibn Munim al-Abdari came from Denia in al-Andalus and settled in Marrakech, teaching at the Mansuriyya dome near the mosque. Birth and arrival years are unknown. Abd al-Aziz al-Naqr reports a researcher's suggested invitation from al-Mansur, not an invitation document we read. He distinguishes the Sicilian Muhammad ibn Isa ibn Abd al-Munim: a similar name does not transfer books between people 2.

    Individual Muslim identification rests on the institutional book article explicitly including him among Muslim scholars, corroborated by religious self-expression reported in Djebbar, not his name or home. The separate Sunni frame is the museum's general frame, not personal Maliki attestation or affiliation inferred from Almohad patronage. Djebbar reports prefatory praise of Ibn Tumart and the ruler; this remains attributed rhetoric, not the museum's verdict or a complete personal creed biography 3 4.

    Teaching and medicine

    The biography reports learning from his father, practising medicine around thirty, teaching and mathematical distinction. Mentally reviewing Euclid in reverse before sleep is an anecdote attributed to an older biography, not our observation or a memory test. Praise for a physician is not modern evidence of a drug's efficacy or grounds to offer a treatment recipe 5.

    Students include al-Sharif and Ibn al-Saddad al-Najjar; the reported nickname al-Sharif is not our genealogical verification. The article reports reception by Ibn al-Banna, Ibn Haydur and Ibn Zakariyya al-Gharnati, with Ibn Khaldun's account of sources for Raf al-hijab. Receiving a book's ideas does not establish personal discipleship; we have not read every intermediary text 6.

    Works and limits

    Fiqh al-hisab treats integers and fractions; sectionXI counts selections and arrangements within a linguistic project. Its combinatorial development is not invention of every count or numerical triangle. Djebbar acknowledges earlier work by al-Khalil and al-Karaji 7 8.

    Al-Naqr lists other arithmetic, geometry and music works, a title not established and manuscript reports. We therefore do not say everything except Fiqh al-hisab is lost, or claim to have inspected those copies. An unidentified title invites no guessed correction. The source pairs626AH/1228 for death; no independent conversion, exact day or speculative birth year is added 9.

    Djebbar's earlier study lacked composition location; the later biography adds older Marrakech evidence. Both knowledge layers remain visible. We read the institutional overview and selected modern study sections, not original biography, arithmetic manuscript or2005 edition. Political praise and a later copy's date do not identify the moment a proof was devised 10 11.
