Narrated By Jubair bin Mutim : I heard Allah's Apostle saying, 'I have several names: I am Muhammad and I am Ahmad, and I am Al-Mahi with whom Allah obliterates Kufr (disbelief), and I am Al-Hashir (gatherer) at whose feet (i.e. behind whom) the people will be gathered (on the Day of Resurrection), and I am Al-Aqib (i.e. who succeeds the other prophets in bringing about good)."
