I am Muhammad and I am Ahmad, and I am al-Mahi (the obliterator) by whom unbelief would be obliterated, and I am Hashir (the gatherer) at whose feet mankind will be gathered, and I am 'Aqib (the last to come) after whom there will be no Prophet.
Sahih Muslim Book 43, Hadith 163
← Previous Hadith Ibn 'Abbas reported that Allah's Messenger (ﷺ) stayed in Mecca for fifteen years (after his advent as a Prophet) and he heard the voice of Gabriel and saw his radiance for seven years but did not see any visible form, and then received revelation for ten years, and he stayed in Medina for ten years.

Sahih Muslim Book 43, Hadith 162 Next Hadith → I have many names: I am Muhammad, I am Ahmad, I am al-Mahi through whom Allah obliterates unbelief, and I am Hashir (the gatherer) at whose feet people will be gathered, and I am 'Aqib (after whom there would be none), and Allah has named him as compassionate and merciful.
