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. (Using translation from Muslim 2354a)   

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ إِنَّ لِي أَسْمَاءً أَنَا مُحَمَّدٌ وَأَنَا أَحْمَدُ وَأَنَا الْمَاحِي الَّذِي يَمْحُو اللَّهُ بِيَ الْكُفْرَ وَأَنَا الْحَاشِرُ الَّذِي يُحْشَرُ النَّاسُ عَلَى عَقِبِي وَأَنَا الْعَاقِبُ وَالْعَاقِبُ الَّذِي لَيْسَ بَعْدَهُ أَحَدٌ
