أحمد:٢٣٤٧٥حَدَّثَنَا رَوْحٌ حَدَّثَنَا سَعِيدُ بْنُ أَبِي عَرُوبَةَ عَنْ قَتَادَةَ عَنْ عَبْدِ الرَّحْمَنِ بْنِ سَلَمَةَ الْخُزَاعِيِّ عَنْ عَمِّهِ قَالَ

غَدَوْنَا مَعَ رَسُولِ اللهِ ﷺ صَبِيحَةَ عَاشُورَاءَ وَقَدْ تَغَدَّيْنَا فَقَالَ أَصُمْتُمْ هَذَا الْيَوْمَ؟ قَالَ قُلْنَا قَدْ تَغَدَّيْنَا قَالَ فَأَتِمُّوا بَقِيَّةَ يَوْمِكُمْ
