"...and giving glad tidings of a messenger who will come after me, whose name is Aḥmad."
Mālik ibn Anas, on the authority of al-Zuhrī, on the authority of Ibn Jubayr ibn Muṭʿim, who said: The Messenger of Allah (ﷺ) said: "I am Aḥmad, and I am Muḥammad, and I am al-Māḥī (the Effacer) by whom Allah effaces disbelief, and I am al-Ḥāshir (the Gatherer) at whose heels the people shall be gathered, and I am al-ʿĀqib (the Last), meaning: the final [Prophet]."
﴿وَمُبَشِّرًا بِرَسُولٍ يَأْتِي مِنْ بَعْدِي اسْمه أَحْمد﴾.
مَالِكُ بْنُ أَنَسٍ، عَنِ الزُّهْرِيِّ، عَنِ ابْنِ جُبَيْرِ بْنِ مُطْعِمٍ قَالَ: قَالَ رَسُولُ اللَّهِ ﷺ " أَنَا أَحْمَدُ وَأَنَا مُحَمَّدٌ، وَأَنَا الْمَاحِي الَّذِي يَمْحُو اللَّهُ بِي الْكُفْرَ، وَأَنَا الْحَاشِرُ الَّذِي يُحْشَرُ النَّاسُ عَلَى عَقِبِي، وَأَنَا الْعَاقِبُ يَعْنِي: الآخِرَ ".
