[Machine] The sons of Al-Harith ibn Ka'b came to meet the Messenger of Allah ﷺ. I entered upon the Prophet ﷺ and greeted him, and he said, "Welcome, and peace be upon you. Where have you come from?" I said, "O Messenger of Allah, my father and mother are from the tribe of Al-Harith, and they sent me to you with the message of Islam." He said, "Welcome to you. What is your name?" I said, "My name is Akbar." He said, "No, you are Bashir." So the Prophet ﷺ named him Bashir.

أَنَّ بَنِي الْحَارِثِ بْنِ كَعْبٍ وَفَّدُوهُ إِلَى رَسُولِ اللهِ ﷺ قَالَ فَدَخَلْتُ عَلَى النَّبِيِّ ﷺ فَسَلَّمْتُ عَلَيْهِ فَقَالَ «مَرْحَبًا وَعَلَيْكَ السَّلَامُ مِنْ أَيْنَ أَقْبَلْتَ؟» فَقُلْتُ يَا رَسُولَ اللهِ بِأَبِي أَنْتَ وَأُمِّي بَنُو الْحَارِثِ وَفَّدُونِي إِلَيْكَ بِالْإِسْلَامِ فَقَالَ «مَرْحَبًا بِكَ مَا اسْمُكَ؟» قُلْتُ اسْمِي أَكْبَرُ قَالَ «بَلْ أَنْتَ بَشِيرٌ» فَسَمَّاهُ النَّبِيُّ ﷺ بَشِيرًا
