Jubayr bin Mut'im Radiyallahu 'Anhu says:
"Rasulullah Sallallahu 'Alayhi Wasallam said: 'I have many names, I am Muhammad, I am Ahmad, I am Maahi (the one who erases-eradicates) through whom Allah has eradicated kufr. I am Haashir, whom Allah will raise first on the day of qiyaamah, the whole ummah will be judged before my feet on the day of qiyaamah. I am 'Aaqib (the one who comes last), and that 'Aaqib, after whom there shall be no other nabi'".
Hudhayfah Radiyallahu 'Anhu reports:
"I once met Rasulullah Sallallahu 'Alayhi Wasallam on one of the roads of Madinah. He said, I am Muhammad, and I am Ahmad, and I am the Nabi of Mercy, the Nabi of Repentance, I am Muqaffaa, I am Haashir, and Nabiyyul Malaahim".
