[Machine] I heard the Messenger of Allah ﷺ say, "Indeed, this day is the day of Ashura, and Allah has not prescribed fasting for you. So whoever wishes to fast, let them fast, and whoever wishes to break their fast, let them break it." This is the wording of the Hadith narrated by Al-Qa'nabi, and Al-Shafi'i added in his narration, "And I am fasting, so whoever wishes, let them fast, and the rest is the same in meaning."  

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ إِنَّ هَذَا الْيَوْمَ يَوْمُ عَاشُورَاءَ وَلَمْ يَكْتُبِ اللهُ عَلَيْكُمْ صِيَامَهُ فَمَنْ شَاءَ فَلْيَصُمْ وَمَنْ شَاءَ فَلْيُفْطِرْ هَذَا لَفْظُ حَدِيثِ الْقَعْنَبِيِّ وَزَادَ الشَّافِعِيُّ فِي رِوَايَتِهِ وَأَنَا صَائِمٌ وَمَنْ شَاءٌ فَلْيَصُمْ وَالْبَاقِي بِمَعْنَاهُ  

[Machine] Mu'awiyah said from the pulpit of the city, "Where are your scholars, O people of the city? The Messenger of Allah ﷺ used to forbid things like this, and he narrated a story from a group among you, from the Ku'bah of one of them, containing poetry, and he said, 'Verily, the Children of Israel were destroyed when their women began to adopt such actions. Where are your scholars, O people of the city? I heard the Messenger of Allah ﷺ on this day, the Day of Ashura, saying, 'Indeed, I am fasting, so whoever among you wants to fast, let him fast.'"  

قَالَ مُعَاوِيَةُ عَلَى مِنْبَرِ الْمَدِينَةِ أَيْنَ عُلَمَاؤُكُمْ يَا أَهْلَ الْمَدِينَةِ كَانَ رَسُولُ اللهِ ﷺ يَنْهَى عَنْ مِثْلِ هَذِهِ وَأَخْرَجَ قُصَّةً مِنْ كُبَّةٍ مِنْ كُمِّهِ مِنْ شَعْرٍ وَيَقُولُ إِنَّمَا هَلَكَتْ بَنُو إِسْرَائِيلَ حَيْثُ اتَّخَذَتْ نِسَاؤُهُمْ مِثْلَ هَذَا أَيْنَ عُلَمَاؤُكُمْ يَا أَهْلَ الْمَدِينَةِ سَمِعْتُ رَسُولَ اللهِ ﷺ فِي هَذَا الْيَوْمِ يَوْمِ عَاشُورَاءَ يَقُولُ إِنِّي صَائِمٌ فَمَنْ شَاءَ مِنْكُمْ أَنْ يَصُومَ فَلْيَصُمْ  

[Machine] The Prophet ﷺ said, "The day of Ashura is a day that the people of Jahiliyyah used to fast. So whoever among you wishes to fast, let him fast, and whoever dislikes it, let him leave it."  

قَالَ النَّبِيُّ ﷺ وَذُكِرَ يَوْمُ عَاشُورَاءَ عِنْدَهُ كَانَ ح وَأَخْبَرَنَا أَبُو الْحَسَنِ مُحَمَّدُ بْنُ يَعْقُوبَ الْفَقِيهُ أنبأ أَبُو النَّضْرِ الْفَقِيهُ ثنا عُثْمَانُ بْنُ سَعِيدٍ ثنا الطَّيَالِسِيُّ أَبُو الْوَلِيدِ ثنا لَيْثُ بْنُ سَعْدٍ عَنْ نَافِعِ عَنِ ابْنِ عُمَرَ عَنْ رَسُولِ اللهِ ﷺ قَالَ يَوْمُ عَاشُورَاءَ يَوْمٌ كَانَ يَصُومُهُ أَهْلُ الْجَاهِلِيَّةِ فَمَنْ أَحَبَّ مِنْكُمْ أَنْ يَصُومَهُ فَلْيَصُمْهُ وَمَنْ كَرِهَهُ فَلْيَدَعْهُ  

It is a day on which the people of pre-Islamic days observed fast. So he who liked to fast on this day should do so, and he who liked to abandon it should abandon it. 'Abdullah (Allah be pleased with him) did not observe fast except when it coincided (with the days when he was in the habit of observing voluntary fasts during every month). (Using translation from Muslim 1126d)   

أَنَّهُ سَمَعَ رَسُولَ اللهِ ﷺ يَقُولُ فِي يَوْمِ عَاشُورَاءَ إِنَّ هَذَا يَوْمٌ كَانَ يَصُومُهُ أَهْلُ الْجَاهِلِيَّةِ فَمَنْ أَحَبَّ أَنْ يَصُومَهُ فَلْيَصُمْهُ وَمَنْ أَحَبَّ أَنْ يَتْرُكَهُ فَلْيَتْرُكْهُ وَكَانَ عَبْدُ اللهِ لَا يَصُومُهُ إِلَّا أَنْ يُوَافِقَ صِيَامَهُ  

[Machine] The day of Ashura was a day that the Quraysh used to observe fasting during the time of ignorance. When Islam came, the Messenger of Allah ﷺ said, "Whoever wishes to fast, he may do so, and whoever wishes to leave it, he may do so."  

كَانَ يَوْمُ عَاشُورَاءَ يَوْمًا تَصُومُهُ قُرَيْشٌ فِي الْجَاهِلِيَّةِ فَلَمَّا جَاءَ الْإِسْلَامُ قَالَ رَسُولُ اللهِ ﷺ مَنْ شَاءَ صَامَهُ وَمَنْ شَاءَ تَرَكَهُ
