حَدَّثَنِي أَحْمَدُ أَوْ مُحَمَّدُ بْنُ عُبَيْدِ اللَّهِ الْغُدَانِيُّ حَدَّثَنَا حَمَّادُ بْنُ أُسَامَةَ أَخْبَرَنَا أَبُو عُمَيْسٍ عَنْ قَيْسِ بْنِ مُسْلِمٍ عَنْ طَارِقِ بْنِ شِهَابٍ عَنْ أَبِي مُوسَی رَضِيَ اللَّهُ عَنْهُ قَالَ دَخَلَ النَّبِيُّ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ الْمَدِينَةَ وَإِذَا أُنَاسٌ مِنْ الْيَهُودِ يُعَظِّمُونَ عَاشُورَائَ وَيَصُومُونَهُ فَقَالَ النَّبِيُّ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ نَحْنُ أَحَقُّ بِصَوْمِهِ فَأَمَرَ بِصَوْمِهِ
صحیح بخاری · Hadith 3943
Narrated Ibn `Abbas: When the Prophet arrived at Medina he found that the Jews observed fast on the day of 'Ashura'. They were asked the reason for the fast. They replied, "This is the day when Allah caused Moses and the children of Israel to have victory over Pharaoh, so we fast on this day as a sign of glorifying it." Allah's Apostle said, "We are closer to Moses than you." Then he ordered that fasting on this day should be observed.
