Mishkat al-Masabih 29 Excellent Qualities and Description of the Prophet كتاب الفضائل والشمائل 37

وَعَن أبي مُوسَى الْأَشْعَرِيّ قَالَ: كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يُسَمِّي لَنَا نَفْسَهُ أَسْمَاءً فَقَالَ: «أَنَا مُحَمَّدٌ وَأَحْمَدُ وَالْمُقَفِّي وَالْحَاشِرُ وَنَبِيُّ التَّوْبَةِ وَنَبِيُّ الرَّحْمَة» . رَوَاهُ مُسلم

Abu Musa al-Ash`ari told that God’s messenger used to name himself to them in various ways, saying, “I am Muhammad, Ahmad, al-Muqaffi (the follower)[*], al-Hashir, the prophet of repentance and the prophet of mercy.” *This title indicates that he follows other prophets, being the last. Muslim transmitted it.
