3,408 tabi'in, 4,408 tabi' al-tabi'in, 80,000 teacher–student links.

Two generations gathered from 13 classical sources (Ibn Sa'd, al-Tarikh al-Kabir, Tahdhib al-Kamal, Tadhkirat al-Huffaz…). 80,452 teacher–student links, 40 “golden chains” and an interactive silsila reaching back to the Prophet ﷺ. A map with a decade slider, “Did he hear?” — evidence that one narrator heard from another (without a verdict), their own sayings by topic, women, and scholars of 8 regions. Death dates are taken only from the books' text, never estimated.
