حَدَّثَنَا عَبْد اللَّهِ قَالَ حَدَّثَنِي مُحَمَّدُ بْنُ أَبِي بَكْرٍ الْمُقَدَّمِيُّ قَالَ حَدَّثَنَا أَبُو مَعْشَرٍ الْبَرَاءُ قَالَ حَدَّثَنَا ابْنُ حَرْمَلَةَ عَنْ يَحْيَى بْنِ هِنْدِ بْنِ حَارِثَةَ عَنْ أَبِيهِ وَكَانَ مِنْ أَصْحَابِ الْحُدَيْبِيَةِ وَأَخُوهُ الَّذِي بَعَثَهُ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَأْمُرُ قَوْمَهُ بِصِيَامِ يَوْمِ عَاشُورَاءَ وَهُوَ أَسْمَاءُ بْنُ حَارِثَةَ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بَعَثَهُ فَقَالَ مُرْ قَوْمَكَ فَلْيَصُومُوا هَذَا الْيَوْمَ قَالَ أَرَأَيْتَ إِنْ وَجَدْتُهُمْ قَدْ طَعِمُوا قَالَ فَلْيُتِمُّوا بَقِيَّةَ يَوْمِهِمْ.
