مسلم:١١١٥cوَحَدَّثَنَاهُ أَحْمَدُ بْنُ عُثْمَانَ النَّوْفَلِيُّ حَدَّثَنَا أَبُو دَاوُدَ

حَدَّثَنَا شُعْبَةُ بِهَذَا الإِسْنَادِ نَحْوَهُ وَزَادَ قَالَ شُعْبَةُ وَكَانَ يَبْلُغُنِي عَنْ يَحْيَى بْنِ أَبِي كَثِيرٍ أَنَّهُ كَانَ يَزِيدُ فِي هَذَا الْحَدِيثِ وَفِي هَذَا الإِسْنَادِ أَنَّهُ قَالَ عَلَيْكُمْ بِرُخْصَةِ اللَّهِ الَّذِي رَخَّصَ لَكُمْ قَالَ فَلَمَّا سَأَلْتُهُ لَمْ يَحْفَظْهُ
