الكبرى للنسائي:٢٨٦٤أَخْبَرَنَا إِسْمَاعِيلُ بْنُ مَسْعُودٍ قَالَ حَدَّثَنَا بِشْرٌ قَالَ حَدَّثَنَا سَعِيدٌ عَنْ قَتَادَةَ عَنْ عَبْدِ الرَّحْمَنِ الْخُزَاعِيِّ

عَنْ عَمِّهِ أَنَّهُمْ غَدَوْا عَلَى رَسُولِ اللهِ ﷺ يَوْمَ عَاشُورَاءَ وَقَدْ أَصَابُوا مِنَ الْغَدَاءِ فَقَالَ لَهُمْ «أَصُمْتُمُ الْيَوْمَ؟» قَالَ قُلْنَا قَدْ أَصَبْنَا مِنَ الْغَدَاءِ فَأَمَرَنَا أَنْ نُتِمَّ بَقِيَّةَ يَوْمِنَا وَقَالَ لَهُمْ أَتِمُّوا بَقِيَّةَ يَوْمِكُمْ
