question #1 Sahih Muslim 746d, Book 6, Hadith 171 : What significance does participating in the Battle of Uhud hold in Islamic history?

Who is Hisham? He said: The son of ‘Amir. She said: What a fine man he was; he participated in the Battle of Uhud along with the Messenger of Allah (ﷺ). Hakim b. Aflah said: If I ever knew that you do not go to ‘A’isha, I would not have informed you about her hadith (So that you would have gone to her and heard it from her orally).
