Hazrat ‘Ali (radhiyallahu ‘anhu) reports:

Rasulullah (sallallahu ‘alaihi wasallam) sent me as his governor to Yemen. Before departing, I addressed him and said, “O Rasul of Allah (sallallahu ‘alaihi wasallam)! You are sending me to people who are older than me. Furthermore, I am a youngster and I do not have any insight in the field of qadhaa (judicial matters).”
