Coverage & limitations
Isnad chains are currently parsed for 11 of 18 books: the 9 canonical collections (Bukhari, Muslim,
Abu Dawud, Tirmidhi, Nasa'i, Ibn Majah, Ahmad, Malik, Darimi) plus Musannaf Ibn Abi Shaybah and Mishkat al-Masabih.
Not yet covered: Riyad as-Salihin, Al-Adab al-Mufrad, Bulugh al-Maram, Shamail Muhammadiyah,
and the three Forties collections (Nawawi, Qudsi, Shah Waliullah). These books either lack structured isnad
text or use abbreviated chains that require different parsing.
Chain extraction is regex-based (not ML), so some narrators may be split or merged incorrectly.
The top 60 narrators per book are shown; minor narrators are grouped under "Others."
Reading this diagram — glossary of terms
Narrator (node)
A rawi — a person in the chain of transmission. Each box in the diagram is one narrator. The diagram shows the most frequently appearing narrators in the selected book.
Transmission (link)
A line connecting two narrators means one transmitted hadiths to the other. The thickness of the line shows how many hadiths flowed through that teacher–student pair. In hadith science, this is the riwayah — the act of narrating from one’s shaykh.
Min transmissions
Only show narrator pairs who shared at least this many hadiths. Set higher (10+, 20+) to focus on the strongest, most prolific transmission routes. Set lower (2+) to see weaker or rarer connections.
Max narrators
How many of the top narrators to display. At 20, you see only the most prolific transmitters. At 60, you see the full network including less common narrators.
Narrator grade
Colour-coded from Ibn Hajar’s Taqrib al-Tahdhib: Companion (Sahabi), Reliable (Thiqah), Mostly reliable (Sadooq), Weak (Da’if), Abandoned (Matrook).
Flow direction
Left to right: from the earliest narrators (often Companions) toward later transmitters and compilers. The flow mirrors the historical passage of hadith through generations (tabaqat).
