Jubair b. Mut'im told that he heard the Prophet say, "I have names. I am Muhammad, I am Ahmad, I am al-Mahi (the obliterator) by whom God obliterates infidelity, I am al-Hashir (the gatherer) who will gather mankind at my feet, I am al-'Aqib (the last in succession), al- `Aqib being the one after whom there will be no prophet."
(Bukhari and Muslim.)
