Narrated Jafar bin 'Amr bin Umaiya: I went out with 'Ubaidullah bin 'Adi Al-Khaiyar. When we reached Hims (i.e. a town in Syria), 'Ubaidullah bin 'Adi said (to me), "Would you like to see Wahshi so that we may ask him about the killing of Hamza?" I replied, "Yes." Wahshi used to live in Hims. We enquired about him and somebody said to us, "He is that in the shade of his palace, as if he were a full water skin." So we went up to him, and when we were at a short distance from him, we greeted him and he greeted us in return. 'Ubaidullah was wearing his turban and Wahshi could not see except his eyes and feet. 'Ubaidullah said, "O Wahshi! Do you know me?" Wahshi looked at him and then said, "No, by Allah! But I know that 'Adi bin Al-Khiyar married a woman called Um Qital, the daughter of Abu Al-Is, and she delivered a boy for him at Mecca, and I looked for a wet nurse for that child. (Once) I carried that child along with his mother and then I handed him over to her, and your feet resemble that child's feet." Then 'Ubaidullah uncovered his face and said (to Wahshi), "Will you tell us (the story of) the killing of Hamza?" Wahshi replied "Yes, Hamza killed Tuaima bin 'Adi bin Al-Khaiyar at Badr (battle) so my master, Jubair bin Mut'im said to me, 'If you kill Hamza in revenge for my uncle, then you will be set free." When the people set out (for the battle of Uhud) in the year of 'Ainain ..'Ainain is a mountain near the mountain of Uhud, and between it and Uhud there is a valley.. I went out with the people for the battle. When the army aligned for the fight, Siba' came out and said, 'Is there any (Muslim) to accept my challenge to a duel?' Hamza bin 'Abdul Muttalib came out and said, 'O Siba'. O Ibn Um Anmar, the one who circumcises other ladies! Do you challenge Allah and His Apostle?' Then Hamza attacked and killed him, causing him to be non-extant like the bygone yesterday. I hid myself under a rock, and when he (i.e. Hamza) came near me, I threw my spear at him, driving it into his umbilicus so that it came out through his buttocks, causing him to die. When all the people returned to Mecca, I too returned with them. I stayed in (Mecca) till Islam spread in it (i.e. Mecca). Then I left for Taif, and when the people (of Taif) sent their messengers to Allah's Apostle, I was told that the Prophet did not harm the messengers; So I too went out with them till I reached Allah's Apostle. When he saw me, he said, 'Are you Wahshi?' I said, 'Yes.' He said, 'Was it you who killed Hamza?' I replied, 'What happened is what you have been told of.' He said, 'Can you hide your face from me?' So I went out when Allah's Apostle died, and Musailamah Al-Kadhdhab appeared (claiming to be a prophet). I said, 'I will go out to Musailamah so that I may kill him, and make amends for killing Hamza. So I went out with the people (to fight Musailamah and his followers) and then famous events took place concerning that battle. Suddenly I saw a man (i.e. Musailamah) standing near a gap in a wall. He looked like an ash-colored camel and his hair was dishevelled. So I threw my spear at him, driving it into his chest in between his breasts till it passed out through his shoulders, and then an Ansari man attacked him and struck him on the head with a sword. 'Abdullah bin 'Umar said, 'A slave girl on the roof of a house said: Alas! The chief of the believers (i.e. Musailamah) has been killed by a black slave."
