Ahmad also narrated it (3/295) with an authentic chain meeting the criteria of both al-Bukhari and Muslim.
There are two further routes from Jabir:
The first is through al-Aʿmash, from Abu Sufyan, from Jabir. Muslim, al-Nasaʾi, and Ibn Majah narrated it.
The other is through Sharik, from Abdullah ibn Muhammad ibn ʿAqil, from him. Ahmad narrated it (3/332, 339, 394). This is a good chain, but neither version contains the addition.
The fourth is Tariq ibn Ushaym al-Ashjaʿi, the father of Abu Malik, in a report attributed directly to the Prophet, but without that addition. Al-Tabarani narrated it in al-Kabir (The Major Collection). Al-Haythami said (1/25): “Its narrators have been deemed trustworthy.”
I say: It is found in Muslim and elsewhere with the wording: “Whoever declares Allah to be One.” It will come later, Allah willing.
The fifth is Aws ibn Abi Aws al-Thaqafi, who said:
“I came to the Messenger of Allah as part of the delegation of Thaqif. He was in a tent, and everyone in it fell asleep except me and the Messenger of Allah. Then a man came and spoke privately with him, saying: ‘Go and kill him.’ He then said: ‘Does he not testify that there is no god worthy of worship but Allah?’ He replied: ‘Yes, but he says it merely to protect himself.’ He said: ‘Leave him be.’” He then went on to mention the hadith.
Al-Nasaʾi, al-Darimi (2/218), al-Tayalisi, no. 1109, and Ahmad (4/8) narrated it through Shuʿbah, from al-Nuʿman ibn Salim, who said: “I heard Aws say...” This is an authentic chain meeting Muslim’s criteria.
Samak also corroborated him from al-Nuʿman with the same report. Al-Nasaʾi then narrated it, as did Ibn Majah (2/457) and Ahmad, through the route of Abdullah ibn Bakr
