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) in the time of Ignorance (Jahiliyyah) in the market of Dhu al-Majaz. He (peace and blessings be upon him) was saying: "O people, say 'La ilaha illallah' (There is no god but Allah), and you will succeed." He said: He (peace and blessings be upon him) was repeating it again and again, and the people had gathered around him (peace and blessings be upon him) and were following him (peace and blessings be upon him), while behind him (peace and blessings be upon him) was a squint-eyed man with two braids of hair and a bright face, saying: He is one who has abandoned his religion, and a liar. I asked: Who is this? The people said: This is his uncle, Abu Lahab. I have cited Abd al-Rahman bin Abi al-Zinad as corroboration following the example of the two of them (Imam Bukhari and Muslim), for both of them also cited him as corroboration.
