[Machine] Al-Mufadhdhal ibn Ghassan al-Ghilani narrated about those who were known for their hypocrisy during the time of the Prophet ﷺ. He said, "Al-Harith ibn Suwayd ibn Samit, from the Banu Amr ibn Awf, participated in the Battle of Badr. He was the one who killed Al-Mijdar on the day of Uhud in revenge, so the Prophet ﷺ killed him with it."  

البيهقي:١٦٠٦٢وَأَخْبَرَنَا أَبُو مُحَمَّدٍ السُّكَّرِيُّ بِبَغْدَادَ أنبأ أَبُو بَكْرٍ الشَّافِعِيُّ ثنا جَعْفَرُ بْنُ مُحَمَّدِ بْنِ الْأَزْهَرِ

ثنا الْمُفَضَّلُ بْنُ غَسَّانَ الْغِلَانِيُّ وَهُوَ يَذْكُرُ مَنْ عُرِفَ بِالنِّفَاقِ فِي عَهْدِ النَّبِيِّ ﷺ قَالَ وَالْحَارِثُ بْنُ سُوَيْدِ بْنِ صَامِتٍ مِنْ بَنِي عَمْرِو بْنِ عَوْفٍ شَهِدَ بَدْرًا وَهُوَ الَّذِي قَتَلَ الْمِجْذَرَ يَوْمَ أُحُدٍ غِيلَةً فَقَتَلَهُ بِهِ نَبِيُّ اللهِ ﷺ
