islamlab — The Islamic Sciences Corpus

The Islamic sciences other than Qur'an and hadith, as their authors wrote them: 3,862 works by scholars who died between the 0st and the 14th Hijri century, cut along their own chapter and biographical-entry boundaries into 1,847,280 units (3.38 billion characters of Arabic), each carrying the volume and page it sits on so a quotation can be cited rather than merely produced.

Scope is Ahl al-Sunnah wa'l-Jamāʿah, and the gate is the author, not the title. A work enters only if its author died by 1350 AH, so every text here is in the public domain and is carried verbatim.

islamlab is a volunteer effort. Our aim is to present these works carefully and at high quality, and to help them travel faithfully — in the spirit in which they were written — not to claim them as ours. Who to thank, and what we consulted without ever quoting, is set out in SOURCES.md.

How the rows are shaped

• works is the spine: one row per work, carrying work_id, our category and subcategory, madhhab where the work declares one, the Arabic and transliterated title and author, the author's death year in both calendars, and the size of the text. source says which library our copy came through and text_quality warns where the digitisation was never proof-read. Everything else joins to it on work_id.
• The eight science configs hold the text. A row is one heading-delimited unit: heading and heading_path place it in the book, kind says whether it is a section or a biographical entry, and page_start / page_end anchor it in the printed edition. markers carries the structural flags the source records about that heading — auto and check say how the heading was found, bio_man / bio_wom / dic_top / dic_lex / dic_nis / dic_bib say what kind of entry it opens, and paratext / editor warn that the block is the modern edition's apparatus rather than the author's text. Filter on it or ignore it; it is never mixed into the Arabic.
• passages is the same text re-cut to ~1,200 characters on sentence boundaries for retrieval, each chunk carrying a ready Arabic citation and the unit_id it came from.
• parallel_en is the corpus's one multilingual seam: sentence-aligned Arabic–English for seventeen works that have a published translation — among them al-Shāfiʿī's Risāla, Ibn Khaldūn's Muqaddima, Ibn Khallikān's Wafayāt, Ibn Baṭṭūṭa's Riḥla and Ibn Ḥazm's Ṭawq al-Ḥamāma. It is a separate table because it is a different kind of thing: a translation is someone's reading, not the author's words.

The Arabic itself is untouched: continuation lines are rejoined, page stamps and editorial flags are lifted into their own columns, whitespace is collapsed, and no letter or vowel is altered. The one substitution is notational — where the source brackets a Qur'anic quotation with its own ASCII markers, the text carries ﴿ ﴾ instead, which is how Arabic prints it. There is no search-normalised copy; strip the diacritics yourself if your retriever wants them gone.

Where this sits

Three organisations, three gates; a work belongs to exactly one of them.

Dataset family	What it holds
quranlab/*	Qur'an, translations, tafsīr, qirā'āt, hadith text and its commentary, recitation
risaleinur/*	The Risale-i Nur corpus and its derivatives
islamlab/*	Every other Islamic science — this dataset

Training products derived from this corpus — text for domain adaptation, retrieval pairs with hard negatives, and citation questions with a work-level held-out split — are in islamlab/islamic-sciences-training.

The line that matters most in practice: hadith text belongs to quranlab/hadith; the sciences built about that text — narrator criticism, ʿilal, muṣṭalaḥ, takhrīj — are the rijal config here.

Notes

• Keys are stable: work_id, unit_id ({work_id}:{seq}), passage_id.
• subcategory and madhhab are empty where the work does not declare one. An empty cell means we do not know, never that the answer is "none".
• Corrections, additions and removal requests are welcome on the Community tab, and are acted on promptly.

License

The works are public domain; the machine-readable transcriptions they reached us through are licensed CC BY-NC-SA 4.0, so this dataset carries the same terms — attribute, keep it non-commercial, share alike. The details are in LICENSES.md and the credits in SOURCES.md.
