صحيح البخاري#2004Sahihحَدَّثَنَا أَبُو مَعْمَرٍ، حَدَّثَنَا عَبْدُ الْوَارِثِ، حَدَّثَنَا أَيُّوبُ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ سَعِيدِ بْنِ جُبَيْرٍ، عَنْ أَبِيهِ، عَنِ ابْنِ عَبَّاسٍ ـ رضى الله عنهما ـ قَالَ قَدِمَ النَّبِيُّ صلى الله عليه وسلم الْمَدِينَةَ، فَرَأَى الْيَهُودَ تَصُومُ يَوْمَ عَاشُورَاءَ، فَقَالَ " مَا هَذَا ". قَالُوا هَذَا يَوْمٌ صَالِحٌ، هَذَا يَوْمٌ نَجَّى اللَّهُ بَنِي إِسْرَائِيلَ مِنْ عَدُوِّهِمْ، فَصَامَهُ مُوسَى. قَالَ " فَأَنَا أَحَقُّ بِمُوسَى مِنْكُمْ ". فَصَامَهُ وَأَمَرَ بِصِيَامِهِ.
Narrated Ibn `Abbas:The Prophet (ﷺ) 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 (ﷺ) 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)
Scholarly Authentication
The label above is the grade most of these scholars gave — one dissenting opinion no longer speaks for all of them. If any scholar calls a narration fabricated, that verdict is shown instead, whatever the others say. Each scholar's own wording:
Every narration in Sahih al-Bukhari is accepted as Sahih (authentic) by the established status of the book.
