question #3 Sahih al-Bukhari 3970, Book 64, Hadith 23 : What can be inferred about the bravery and readiness of Ali in battles from historical accounts?

A man asked Al-Bara’ and I was listening, “Did `Ali take part in (the battle of) Badr?” Al-Bara’ said,
“(Yes). he even met (his enemies) in a duel and was clad in two armors (one over the other).
