Did Ali ibn Abi Talib uproot the gate of Khaybar?

There are narrations stating that Ali ibn Abi Talib, may Allah be pleased with him, carried the gate of Khaybar and used it as a shield. However, these narrations are not authentic due to their inclusion of discontinuity (in isnad), unknown narrators, and weakness. A number of scholars, including Al-Dhahabi, Ibn Kathir, Al-Sakhawi, and Ibn Taymiyyah, have rejected these narrations. This, however, does not negate Ali's bravery and strength, which have been proven in other instances.
