Hadith 34:14
Da'if (Al-Albani)
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
