حَدَّثَنِي مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا غُنْدَرٌ، حَدَّثَنَا شُعْبَةُ، عَنْ أَبِي بِشْرٍ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ، عَنِ ابْنِ عَبَّاسٍ، قَالَ قَدِمَ النَّبِيُّ صلى الله عليه وسلم الْمَدِينَةَ وَالْيَهُودُ تَصُومُ عَاشُورَاءَ فَقَالُوا هَذَا يَوْمٌ ظَهَرَ فِيهِ مُوسَى عَلَى فِرْعَوْنَ‏.‏ فَقَالَ النَّبِيُّ صلى الله عليه وسلم لأَصْحَابِهِ ‏\n"‏ أَنْتُمْ أَحَقُّ بِمُوسَى مِنْهُمْ، فَصُومُوا ‏"‏‏.‏
