It is narrated from Sayyiduna Rabi'ah bin Abbad al-Dili (may Allah be pleased with him) that he said: "I saw the Messenger of Allah (peace and blessings be upon him), before he emigrated, in the market of Dhu al-Majaz. He (peace and blessings be upon him) was going round to the people and saying: 'O people, indeed Allah, the Mighty and Majestic, commands you to worship Him and not to associate anything with Him.' 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?' The people said: 'This is his uncle, Abu Lahab.'"
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Zayd (may Allah have mercy on him) except Sa'id (may Allah have mercy on him), and Abd al-Samad (may Allah have mercy on him) is alone in narrating it from him."
