The Nine Books of hadith

The Ahadith tab is not a quotes app. It carries the nine canonical collections — Sahih al-Bukhari, Sahih Muslim, Sunan Abi Dawud, Jami' al-Tirmidhi, Sunan al-Nasa'i, Sunan Ibn Majah, the Muwatta of Malik, Sunan al-Darimi and the Musnad of Ahmad — and then gives you the apparatus that scholars actually use. Read the isnad as the source marks it, with the transmission formula each narrator used. Open the chain as a drawn tree. Follow a narrator to every hadith they carry. See the takhrij: the consecrated formulas, computed from attestations rather than typed by hand. Compare two wordings of the same matn word by word. Sweep the whole corpus for a phrase, including where no cross-reference was ever established. One rule holds the whole tab together: nothing is inferred. Every number is a count over the corpus, every name comes from markup, every verdict is signed by a named scholar — and where the corpus is silent, the screen says so rather than filling the gap with a guess.

  • 62,535 hadiths across the nine books — Bukhari 7,103, Muslim 5,445, Abu Dawud 4,601, al-Tirmidhi 3,888, al-Nasa'i 5,665, Ibn Majah 4,331, Malik 1,756, al-Darimi 3,368, Ahmad 26,378
  • Isnad read from the source markup, with each transmission formula
  • Isnad tree drawn with rails, unfolded a branch at a time
  • Takhrij with the consecrated formulas — muttafaq 'alayh requires the same Companion, so the count is 24,361 and not 37,075
  • Narrator directory: follow a name through everything they transmit
  • Word-by-word matn comparison, and a similar-wording sweep across the corpus
  • Personal collections, a Leitner review cycle, and a share that carries the reference
  • The corpus downloads once, then the whole tab works offline
How it works

How it works


  1. 01

    Open the Ahadith tab

    The corpus is fetched once; after that the whole tab runs on the device.

  2. 02

    Find a hadith

    Browse the nine shelves, follow a topic, search the text, or start from the hadith of the day.

  3. 03

    Open the dossier

    From any hadith, read the isnad, open the chain as a tree, see the takhrij, or follow a narrator through the corpus.

  4. 04

    Keep what matters

    File it in a collection of your own, put it into the review cycle, or share it.

FAQ

Questions about this feature


Which collections are included?

The nine canonical books: Sahih al-Bukhari, Sahih Muslim, Sunan Abi Dawud, Jami' al-Tirmidhi, Sunan al-Nasa'i, Sunan Ibn Majah, the Muwatta of Malik, Sunan al-Darimi and the Musnad of Ahmad.

Does it really show the chain of transmission?

Yes, and it reads it from the markup rather than guessing. A link between two narrators is drawn only where the source writes a transmission formula between them. Where the source is silent — as in tahwil — no link is drawn, because drawing one would invent a transmission that never happened.

What does the takhrij tell me?

Where else the hadith is attested, and under which consecrated formula: muttafaq 'alayh, rawahu al-jama'a, infarada bihi. The strict mode requires the same Companion in both Sahihs — counting every occurrence regardless would give 37,075 instead of 24,361 and make the muhaddithun say what they did not say.

Does the hadith tab work offline?

After the corpus has been fetched once, yes — search, isnad, takhrij, narrators and your own collections all run on the device.

Glossary

Hadith حَدِيث
A report of what the Prophet Muhammad ﷺ said, did, or tacitly approved. Each consists of a matn (the text) and an isnad (the chain of people who transmitted it).
Kutub al-Tis'a الكُتُب التِّسْعَة
The nine collections treated as the working canon of Sunni hadith: the two Sahihs (al-Bukhari, Muslim), the four Sunan (Abu Dawud, al-Tirmidhi, al-Nasa'i, Ibn Majah), the Muwatta of Malik, the Sunan of al-Darimi and the Musnad of Ahmad.
Isnad إِسْنَاد
The chain of narrators through which a report reached the compiler — each naming the one before, back to a Companion and then to the Prophet ﷺ. The science of hadith is largely the science of judging these chains.
Matn مَتْن
The text of a hadith — what was actually said — as opposed to the isnad that carries it. Two sound chains often deliver slightly different wordings of the same report.
Takhrij تَخْرِيج
Tracing a hadith to every collection that records it, and stating the result in the consecrated formulas — muttafaq ‘alayh when both Sahihs have it, rawahu al-jama‘a when the major collections do, infarada bihi when only one does.
Muttafaq 'alayh مُتَّفَقٌ عَلَيْه
Said of a hadith recorded by both al-Bukhari and Muslim, from the same Companion. The strongest ordinary grading a report can carry, and the reason the phrase is used as a shorthand for reliability.
Sighat al-ada' صِيغَة الأَدَاء
The words a narrator uses to say how they received a report — haddathana ('he narrated to us'), akhbarani ('he informed me'), sami‘tu ('I heard'), 'an ('from'). It is the first thing a critic reads in a chain, because it says how direct the contact was.
Sahabi صَحَابِيّ
A Companion of the Prophet ﷺ — someone who met him as a believer. Every isnad ends at one, which is why the Companion at the head of a chain identifies the report as much as its wording does.
Muhaddith مُحَدِّث
A scholar of hadith — one who knows the reports, the narrators, and the criticism levelled at each. The verdicts EsSiraj displays are theirs, and are shown signed rather than summarised.
