1145
Musnad AhmedIt was narrated that "Amr bin Murrah said: I heard Abul-Bakhtari At-Ta"i say: Someone who heard ‘Ali (رضي الله عنها) told me that he said:
When the Messenger of Allah (ﷺ) sent me to Yemen, I said: Are you sending me when I am young and I do not know much about judging? The Messenger of Allah (ﷺ) struck my chest and said: Go, for Allah, may He be glorified and exalted, will make your tongue steadfast and guide your heart." He said: I never found it difficult to judge between two people.
