Hadith and Hadith Sciences (Mustalah al-Hadith)
Mustalah al-hadith is the terminology by which a report is dissected into isnad and matn and then graded. The exam tests definitions, the conditions of authenticity, and the classification of a chain or text into the correct technical category. Precision of terms carries the marks; the ruling that follows is usually secondary.
Core rules and concepts
- Anatomy: isnad (the chain of narrators), matn (the wording), khabar and athar (broader terms).
- By number of narrators: mutawatir (a large number in every generation, precluding collusion, yielding certainty); ahad, subdivided into mashhur, 'aziz (two narrators) and gharib (one).
- Five conditions of sahih: continuous chain (ittisal), integrity of narrators ('adalah), precise retention (dabt), absence of shudhudh (no contradiction of a stronger report), absence of a hidden defect ('illah).
- Hasan meets the same conditions with slightly weaker retention; hasan li-ghayrihi is a da'if report supported by another route.
- By chain shape: musnad (traced to the Prophet), muttasil, mursal (a Successor attributes directly to the Prophet), munqati' (a break anywhere before the end), mu'dal (two consecutive narrators missing), mudallas, mu'allal.
- By strength of text: shadhdh (a reliable narrator contradicts a stronger authority), munkar (a weak narrator contradicts), matruk, mawdu' (fabricated).
Worked example
Chain: 'Al-Hasan al-Basri said: the Messenger of God said...' Analysis: al-Hasan is a Successor, so the Companion link is missing at the top of the chain; the report is mursal. Under al-Shafi'i's rule, a mursal is accepted only if supported by another independent route (musnad or another mursal from a different source) or by the practice of scholars. If such support exists it is graded hasan li-ghayrihi; if not it remains da'if and cannot establish an obligation.
Traps that cost marks
- Calling any break a mursal; mursal is specific to a Successor's direct attribution.
- Confusing shadhdh (reliable but contradicting a stronger authority) with munkar (weak, contradicting).
- Adding conditions to sahih beyond the five, such as 'the narrator must be a faqih'.
- Treating mutawatir as requiring a fixed number (some say ten, some forty) rather than a number yielding certainty.
