Sayyiduna Hudhayfah (may Allah be pleased with him) narrates: Once I was walking along a road of Madinah when I heard the Prophet (peace and blessings be upon him) saying: "I am Muhammad, I am Ahmad, I am the Prophet of Mercy, the Prophet of Repentance, al-Hashir (the Gatherer), al-Muqaffi (the one who came last) and the Prophet of the Great Battles (al-Malahim)."
Imam Ahmad and Imam al-Bazzar recorded it. The narrators of Imam Ahmad are the narrators of the "Sahih", except for Asim bin Bahdalah, and he is thiqah (trustworthy), though there is weakness in his memory.
Sayyiduna Jabir bin Abdullah (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "I am Ahmad, I am Muhammad, and I am al-Hashir (the Gatherer), at whose feet the people will be gathered; and I am al-Mahi (the Effacer), through whom Allah Almighty will efface disbelief. When the Day of Resurrection comes, the 'Banner of Praise' will be with me, and I will be the leader of the 'Messengers' and their intercessor."
Imam al-Tabarani recorded it in al-Mu'jam al-Kabir and al-Mu'jam al-Awsat; its chain contains a narrator, Urwah bin Marwan, about whom it has been said: He is not strong; the remaining narrators of this report have been declared trustworthy.
Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) reports that the Prophet (peace and blessings be upon him) said: "I am Ahmad, Muhammad, al-Hashir (the Gatherer), al-Muqaffi (the one who came last) and al-Khatam (the Seal)."
Imam al-Tabarani recorded it in al-Mu'jam al-Saghir and al-Mu'jam al-Awsat.
