Al-Adab Al-Mufrad, Book 34, Hadith 14 (In-Book) ⓘ

It is reported that al-Harith ibn Abza said, "I was present at Hunayn with the Prophet, may Allah bless him and grant him peace, and he asked me, 'What is your name?' 'Ghurab,' I replied. He said, 'No, your name is Muslim.'"

حَدَّثَنَا مُحَمَّدُ بْنُ سِنَانٍ، قَالَ‏:‏ حَدَّثَنَا عَبْدُ اللهِ بْنُ الْحَارِثِ بْنِ أَبْزَى قَالَ‏:‏ حَدَّثَتْنِي أُمِّي رَائِطَةُ بِنْتُ مُسْلِمٍ، عَنْ أَبِيهَا قَالَ‏:‏ شَهِدْتُ مَعَ النَّبِيِّ صلى الله عليه وسلم حُنَيْنًا، فَقَالَ لِي‏:‏ مَا اسْمُكَ‏؟‏ قُلْتُ‏:‏ غُرَابٌ، قَالَ‏:‏ لا، بَلِ اسْمُكَ مُسْلِمٌ‏.‏
