Musannaf Ibn Abi Shaybah 34382 — The virtue of Hamzah bin Abd

Ibn Awn (may Allah have mercy on him) said that Umayr bin Ishaq (may Allah have mercy on him) said: Sayyiduna Hamzah (may Allah be pleased with him) used to fight in front of the Prophet (peace and blessings be upon him) with two swords, saying as he went: "I am the lion of Allah, and the lion of the Messenger of Allah (peace and blessings be upon him)."
