Sayyiduna Imran bin Husayn (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "He has eaten food and walked in the markets." The Prophet (peace and blessings be upon him) meant the Dajjal.
Ahmad and al-Tabarani recorded it. Ahmad's chain contains Ali bin Zayd, whose hadith is hasan (good), and the rest of its narrators are the narrators of the Sahih. Al-Tabarani's chain contains Muhammad bin Mansur al-Nahwi al-Ahwazi, whom I do not know, and the rest of its narrators are the narrators of the Sahih.
