الترمذي:٣٦٤٢ – وَقَدْ رُوِيَ عَنْ يَزِيدَ بْنِ أَبِي حَبِيبٍ عَنْ عَبْدِ اللَّهِ بْنِ الْحَارِثِ بْنِ جَزْءٍ مِثْلُ هَذَا حَدَّثَنَا بِذَلِكَ أَحْمَدُ بْنُ خَالِدٍ الْخَلاَّلُ حَدَّثَنَا يَحْيَى بْنُ إِسْحَاقَ السَّيْلَحَانِيُّ حَدَّثَنَا اللَّيْثُ بْنُ سَعْدٍ عَنْ يَزِيدَ بْنِ أَبِي حَبِيبٍ عَنْ عَبْدِ اللَّهِ بْنِ الْحَارِثِ بْنِ جَزْءٍ قَالَ
