الترمذي:٣٧٦٠حَدَّثَنَا أَحْمَدُ بْنُ إِبْرَاهِيمَ الدَّوْرَقِيُّ قَالَ حَدَّثَنَا وَهْبُ بْنُ جَرِيرٍ قَالَ حَدَّثَنِي أَبِي قَالَ سَمِعْتُ الأَعْمَشَ يُحَدِّثُ عَنْ عَمْرِو بْنِ مُرَّةَ عَنْ أَبِي الْبَخْتَرِيِّ عَنْ عَلِيٍّ

أَنَّ النَّبِيَّ ﷺ قَالَ لِعُمَرَ فِي الْعَبَّاسِ إِنَّ عَمَّ الرَّجُلِ صِنْوُ أَبِيهِ وَكَانَ عُمَرُ كَلَّمَهُ فِي صَدَقَتِهِ هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ
