حَدَّثَنَا أَبُو مَعْمَرٍ حَدَّثَنَا عَبْدُ الْوَارِثِ حَدَّثَنَا أَيُّوبُ حَدَّثَنَا عَبْدُ اللَّهِ بْنُ سَعِيدِ بْنِ جُبَيْرٍ عَنْ أَبِيهِ عَنْ ابْنِ عَبَّاسٍ رَضِيَ اللَّهُ عَنْهُمَا قَالَ قَدِمَ النَّبِيُّ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ الْمَدِينَةَ فَرَأَی الْيَهُودَ تَصُومُ يَوْمَ عَاشُورَائَ فَقَالَ مَا هَذَا قَالُوا هَذَا يَوْمٌ صَالِحٌ هَذَا يَوْمٌ نَجَّی اللَّهُ بَنِي إِسْرَائِيلَ مِنْ عَدُوِّهِمْ فَصَامَهُ مُوسَی قَالَ فَأَنَا أَحَقُّ بِمُوسَی مِنْکُمْ فَصَامَهُ وَأَمَرَ بِصِيَامِهِ
صحیح بخاری · Hadith 2004
Narrated Ibn `Abbas: The Prophet came to Medina and saw the Jews fasting on the day of Ashura. He asked them about that. They replied, "This is a good day, the day on which Allah rescued Bani Israel from their enemy. So, Moses fasted this day." The Prophet said, "We have more claim over Moses than you." So, the Prophet fasted on that day and ordered (the Muslims) to fast (on that day).
