Acquiring the Knowledge of Hadith from a Young Age

Muhammed bin Abi Haatim (rahimahullah) narrates the following:

I once asked Imaam Bukhaari (rahimahullah), “How did you commence memorizing Hadith?” Imaam Bukhaari (rahimahullah) replied, “I was inspired by Allah Ta‘ala to commence memorizing the blessed Ahaadith of Rasulullah (sallallahu ‘alaihi wasallam) when I started acquiring ‘ilm at the elementary madrasah.” I asked him, “What was your age at the time?” He replied, “I was ten years old, or perhaps even younger.”
