It is narrated from Sayyiduna Jubayr bin Mut'im (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "I have several names: I am Muhammad, I am Ahmad, I am al-Mahi (the Eraser), through whom Allah erases the disbelievers, I am al-Hashir (the Gatherer), at whose feet the people will be gathered, and I am al-'Aqib (the Last)."
