[Machine] Feed, for this is a day that used to be fasted before Ramadan came down. Then Ramadan came, so this day was abandoned.  

الطبراني:١٠٥٢١حَدَّثَنَا جَعْفَرُ بْنُ أَحْمَدَ الشَّامِيُّ الْكُوفِيُّ ثنا أَبُو كُرَيْبٍ ثنا مُخْتَارُ بْنُ غَسَّانَ ثنا يُونُسُ بْنُ أَبِي يَعْفُورٍ عَنْ أَبِيهِ عَنْ مُسْلِمٍ عَنْ أَبِي سَعْدٍ قَالَ دَخَلْتُ عَلَى ابْنِ مَسْعُودٍ فِي يَوْمِ عَاشُورَاءَ وَهُوَ يَأْكُلُ فَدَخَلَ رَجُلٌ فَقَالَ ابْنُ مَسْعُودٍ «اطْعَمْ» فَقَالَ إِنِّي صَائِمٌ فَقَالَ

«اطْعَمْ إِنَّ هَذَا يَوْمٌ كَانَ يُصَامُ قَبْلَ أَنْ يَنْزِلَ رَمَضَانُ فَنَزَلَ رَمَضَانُ فَتُرِكَ هَذَا الْيَوْمُ»

[Machine] "Do you know the significance of the day of Ashura? Indeed, the Messenger of Allah ﷺ used to observe fasting on it before the month of Ramadan was made obligatory. However, when Ramadan was decreed as obligatory, the fasting of Ashura was abandoned."  

أحمد:٤٠٢٤حَدَّثَنَا يَعْلَى وَابْنُ أَبِي زَائِدَةَ قَالَا حَدَّثَنَا الْأَعْمَشُ عَنْ عُمَارَةَ عَنْ عَبْدِ الرَّحْمَنِ بْنِ يَزِيدَ قَالَ دَخَلَ الْأَشْعَثُ بْنُ قَيْسٍ عَلَى عَبْدِ اللهِ يَوْمَ عَاشُورَاءَ وَهُوَ يَتَغَدَّى فَقَالَ يَا أَبَا مُحَمَّدٍ ادْنُ لِلْغَدَاءِ قَالَ أَوَلَيْسَ الْيَوْمُ عَاشُورَاءَ؟ قَالَ

وَتَدْرِي مَا يَوْمُ عَاشُورَاءَ؟ إِنَّمَا كَانَ رَسُولُ اللهِ ﷺ يَصُومُهُ قَبْلَ أَنْ يَنْزِلَ رَمَضَانُ فَلَمَّا أُنْزِلَ رَمَضَانُ تُرِكَ
