Sayyiduna Jubayr bin Mut'im (may Allah be pleased with him) narrates: "In the days of ignorance (Jahiliyyah) I went out to Syria as a merchant. When I reached the nearest part of Syria, a man from the People of the Book met me and asked: 'Is there a man among you who has claimed prophethood?' I said: 'Yes.' He asked: 'If you saw his picture, would you recognise it?' I said: 'Yes.' Then he took me into a house in which there were many pictures, but I did not see the picture of the Prophet (peace and blessings be upon him). While we were in this state, another man from among them (the People of the Book) came to us and asked: 'What are you about?' We told him, and he took us to his house. As soon as I entered, I saw the picture of the Prophet (peace and blessings be upon him), and I saw a man holding the heel of the Prophet (peace and blessings be upon him). I asked: 'Who is this man holding his (peace and blessings be upon him) heel?' He said: 'There has been no Prophet but that another Prophet came after him, except this Prophet; there is no Prophet after him, and this is the caliph after him.' And it (the picture) matched the appearance and likeness of Sayyiduna Abu Bakr (may Allah be pleased with him)."
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith is narrated from Sayyiduna Jubayr bin Mut'im (may Allah be pleased with him) only with this chain; Muhammad bin Idris, the scribe of al-Humaydi (may Allah have mercy on him), is alone in narrating it."
