Sayyiduna Rabi'ah bin Ibad al-Dili (may Allah be pleased with him) said: I saw the Messenger of Allah (peace and blessings be upon him) at Dhul-Majaz, following the people and calling them to Allah at their camps. Behind him (peace and blessings be upon him) was a cross-eyed man saying: Do not let this man turn you away from the religion of your forefathers. So I asked: Who is this? The people said: His uncle, Abu Lahab.
