Analyze every link of the isnad.

The “haddathana” and “'an” formulas in the chain, teacher–student links, whether the narrators lived in the same era, signs of tadlis, the weakest link, the marfu'/mawquf/maqtu'/mursal type and an isnad graph. Narrator data is gathered from seven books of rijal. The lab issues no verdict — it shows the scholars' evidence.
