isnady

Hadith search built around the isnad — the chain of transmission.

isnady is a desktop application (PySide6, Windows and Linux) for searching hadith across the major collections and seeing why each report has the grade it has: every narrator in the chain, what the scholars of jarh wa ta'dil said about them, and how the chain holds together.

Status: pre-alpha (0.0.4). Search and chains of transmission work today on data you import; narrators, scholars and the rest are being built.

Works now

  • Search across every imported edition. Arabic ignores diacritics and letter forms and finds words with attached prefixes; Turkish and other Latin-script text ignores case and accents. All words, any word or exact phrase; book and language filters.
  • Chains of transmission read from the Arabic text: each narrator, the words that link them (haddathana, akhbarana, 'an ...) with what each means, and whether the chain reaches the Prophet. Where the wording cannot be read with confidence the chain is kept whole, never guessed.
  • Desktop app and command line with the same engine: isnady and isnady-cli.

Planned

  • Search — by text, book, chapter, narrator and grade: mutawatir, sahih, hasan, da'if, mawdu' and the intermediate grades.
  • Narrators — biography, dates, teachers and students, number of narrations, and every recorded verdict with its source.
  • Narrators identified — every name in a chain linked to its narrator, with each narrator's standing and whether each link could have met the next.
  • Reliability scores — derived transparently from classical rankings (for example Ibn Hajar's twelve grades in Taqrib al-Tahdhib), always shown with the verdicts they come from. A score is a conversion of the scholars' judgement, never a new one.
  • Shia rijal — the primary grading follows the Sunni tradition; narrator verdicts from Shia rijal works (al-Najashi, al-Tusi, al-Kashshi, al-Hilli, al-Khoei) are listed per narrator beside the Sunni view.
  • Statistics — narrators, books and grades counted and compared.
  • Learn — the hadith sciences explained: terminology, grading, jarh wa ta'dil, and the classical works.
