Musannaf Ibn Abi Shaybah 39513 — What Abu Bakr (Ibn Abi Shaybah)

It is narrated from Umayr bin Ishaq that in the battle of Uhud Sayyiduna Hamzah (may Allah be pleased with him) was fighting in front of the Prophet (peace and blessings be upon him) with two swords, saying: "I am the lion of Allah." The narrator said: Sayyiduna Hamzah (may Allah be pleased with him) was moving forward and back when he stumbled, fell flat on the back of his neck and slid away, and the coat of mail came open from over the belly of Sayyiduna Hamzah (may Allah be pleased with him). An Abyssinian slave saw him and struck him with a spear or a javelin, which passed right through him.
