Ismaili Ta'wil of al-Huruf al-Muqattaat — The Disconnected Letters: How the Mysterious Opening Letters of 29 Quranic Surahs (Alif Lam Mim, Ya Sin, Ha Mim, etc.) Become in Ismaili Ta'wil the Imam's Signature Written Into the Quran's Opening

In Ismaili ta'wil, al-Huruf al-Muqattaat (الحُرُوفُ المُقَطَّعَة — The Disconnected/Separated Letters; also called fawatih [openings] or al-huruf al-nuraaniyya [luminous letters]; letters that open 29 of the 114 Quranic surahs — Alif Lam Mim [ALM, appears in 2, 3, 29, 30, 31, 32], Ya Sin [YS, 36], Kaf Ha Ya 'Ayn Sad [KHYAS, 19], Ha Mim ['AYN SIN QAF] [42], Ta Sin Mim [TSM, 26, 28], Ta Sin [TS, 27], Sad [S, 38], Qaf [Q, 50], Nun [N, 68], and others; the classical debate: more than 30 different positions have been catalogued by Islamic scholars on what these letters mean: [1] they are divine mysteries known only to God [the dominant position]; [2] they are abbreviations [e.g., ALM = 'ana Allah a'lam' (I, God, know best) — but no classical source validates this]; [3] they are numerological keys [abjad calculation — each letter has a numerical value]; [4] they are challenges to the Arabs that the Quran's eloquence cannot be imitated; [5] they are the letters from which the specific surah is primarily composed; the Ismaili ta'wil: the huruf are the Imam's coded signature in the Quran's structure; just as each Imam has a name whose letters carry meaning, the huruf at the openings of major surahs encode the Imam's identity and authority as the holder of the batin; specific correspondences: Ismaili ta'wil scholars have proposed various correspondences between the huruf groups and the Imamic hierarchy — ALM and the three first Imams; HM and the Imam's ha' [majesty] and mim [Muhammad]; the key principle: the zahir of the huruf is literally the disconnected letters on the page; the batin is the Imam's encoded presence in the revelation from the beginning; the ta'wil of Ya Sin [36:1-2]: 'Ya Sin. By the Quran full of wisdom — you [Prophet] are among the Messengers'; in ta'wil: 'Ya' = the Imam who carries the wisdom; 'Sin' = the silsila [chain] of Imams; the Quran full of wisdom IS the batin that the Imam carries; why 29 surahs: the disconnected letters appear most prominently in surahs that then address major themes of prophethood, Imamate, revelation, and divine guidance — not randomly distributed; their concentration in surahs of Meccan revelation [the deepest theological surahs] supports the Ismaili reading) is the Ismaili engagement with the Quran's most discussed mystery.
