البيهقي:١٨٢٤٧ – أَخْبَرَنَا أَبُو مُحَمَّدٍ عَبْدُ اللهِ بْنُ يَحْيَى بْنِ عَبْدِ الْجَبَّارِ السُّكَّرِيُّ بِبَغْدَادَ أنبأ إِسْمَاعِيلُ الصَّفَّارُ ثنا سَعْدَانُ بْنُ نَصْرٍ ثنا أَبُو مُعَاوِيَةَ عَنْ عُبَيْدِ اللهِ بْنِ عُمَرَ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ ؓ أَنَّ غُلَامًا لَهُ لَحِقَ بِالْعَدُوِّ عَلَى فَرَسٍ لَهُ فَظَهَرَ عَلَيْهَا خَالِدُ بْنُ الْوَلِيدِ ؓ فَرَدَّهُمَا عَلَيْهِ كَذَا قَالَ أَبُو مُعَاوِيَةَ وَقَدْ بَيَّنَ عَبْدُ اللهِ بْنُ نُمَيْرٍ عَنْ

عُبَيْدِ اللهِ مَا كَانَ مِنْهُ عَلَى عَهْدِ النَّبِيِّ ﷺ وَمَا كَانَ بَعْدَهُ
