حَدَّثَنِي يَعْقُوبُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا رَوْحٌ، حَدَّثَنَا شُعْبَةُ، حَدَّثَنَا أَبُو بِشْرٍ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ، عَنِ ابْنِ عَبَّاسٍ ـ رضى الله عنهما ـ قَالَ لَمَّا قَدِمَ رَسُولُ اللَّهِ صلى الله عليه وسلم الْمَدِينَةَ، وَالْيَهُودُ تَصُومُ عَاشُورَاءَ، فَسَأَلَهُمْ، فَقَالُوا هَذَا الْيَوْمُ الَّذِي ظَهَرَ فِيهِ مُوسَى عَلَى فِرْعَوْنَ، فَقَالَ النَّبِيُّ صلى الله عليه وسلم ‏ "‏ نَحْنُ أَوْلَى بِمُوسَى مِنْهُمْ فَصُومُوهُ ‏"‏‏.‏
