حَدَّثَنَا مُحَمَّدُ بْنُ الْمِنْهَالِ، حَدَّثَنَا يَزِيدُ بْنُ زُرَيْعٍ، حَدَّثَنَا سَعِيدٌ، عَنْ قَتَادَةَ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ مَسْلَمَةَ، عَنْ عَمِّهِ، أَنَّ أَسْلَمَ، أَتَتِ النَّبِيَّ صلى الله عليه وسلم فَقَالَ " صُمْتُمْ يَوْمَكُمْ هَذَا " . قَالُوا لاَ . قَالَ " فَأَتِمُّوا بَقِيَّةَ يَوْمِكُمْ وَاقْضُوهُ " . قَالَ أَبُو دَاوُدَ يَعْنِي يَوْمَ عَاشُورَاءَ .
