Umayr bin Ishaq narrates: Sayyiduna Hamzah bin Abd al-Muttalib (may Allah be pleased with him) used to fight in front of the Prophet (peace and blessings be upon him), and he would say: "I am the lion of Allah and the lion of His Messenger."
Al-Tabarani recorded it, and up to the one who said it, its narrators are the narrators of the Sahih.
