Hadith 518430
حَدَّثَنِي مَالِكٌ، عَنِ ابْنِ شِهَابٍ، عَنْ مُحَمَّدِ بْنِ جُبَيْرِ بْنِ مُطْعِمٍ، أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ " لِي خَمْسَةُ أَسْمَاءٍ أَنَا مُحَمَّدٌ وَأَنَا أَحْمَدُ وَأَنَا الْمَاحِي الَّذِي يَمْحُو اللَّهُ بِيَ الْكُفْرَ وَأَنَا الْحَاشِرُ الَّذِي يُحْشَرُ النَّاسُ عَلَى قَدَمِي وَأَنَا الْعَاقِبُ " .
Malik related to me from Ibn Shihab from Muhammad ibn Jubayr ibn Mutim that the Prophet, may Allah bless him and grant him peace, said, "I have five names. I am Muhammad. I am Ahmad. I am al-Mahi (the effacer), by whom Allah effaces kufr. I am al-Hashir (the gatherer), before whom people are gathered. I am al-Aqib (the last)."
