Musannaf Ibn Abi Shaybah 39788 — The report of Abdullah bin Abi Hadrad

It is narrated from Sayyiduna Abdullah bin Abi Hadrad (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) sent us with an expedition to Idam. The narrator said: We met Amir bin al-Adbat. The narrator said: He greeted us with the greeting of the Muslims, so we held back from him. But Muhallim bin Jaththamah attacked him and killed him. When he had killed him, he seized his camel and his goods. When we returned, we presented their matter before the Prophet (peace and blessings be upon him) and told him (peace and blessings be upon him) of it. At this this verse was revealed: "O you who believe, when you go forth in the way of Allah, verify, and do not say to one who shows Islam, 'You are not a believer.'" [Al-Nisa: 94]
