Musannaf Ibn Abi Shaybah 34798 — What they said on cowardice

Harithah bin Mudarrib (may Allah have mercy on him) said that Sayyiduna Ali (may Allah be pleased with him) said: "On the day of the Battle of Badr I saw us seeking protection in the person of the Messenger of Allah (peace and blessings be upon him), and he (peace and blessings be upon him) was the closest of us to the enemy, and he (peace and blessings be upon him) was among the fiercest of people in battle that day."
