It is narrated from Sayyiduna Rabi'ah bin Ibad al-Du'ali (may Allah be pleased with him); he said: I saw the Messenger of Allah (peace and blessings be upon him) at Mina, by their tents, before the emigration to Madinah. He (peace and blessings be upon him) was saying: "O people, Allah commands you to worship Him alone and not to associate anything with Him." He said: Behind him (peace and blessings be upon him) was a man saying: O people, this man is commanding you to abandon the religion of your forefathers. I asked: Who is this man? I was told: This is Abu Lahab. This hadith is sahih on the condition of the two Shaykhs, and all of its narrators are trustworthy and precise. Perhaps both of them, or one of them, imagined that Rabi'ah bin Ibad has no narrator other than Muhammad bin al-Munkadir, whereas Abu al-Zinad Abdullah bin Dhakwan also narrated this very hadith from him.
