Tap each name in the chain.

The isnad is divided into narrator names; when you tap a name, the narrator card appears: how many hadiths they occur in, how many as a primary narrator (Companion), and brief information from al-Dhahabi's «al-Kashif» biographical dictionary (death date, which books narrated from them — automatic matching, to be verified by the teacher). «Hadiths from this narrator» and «Isnad tree» — the different chains of a single hadith side by side, with the same narrator shown in the same color.
