"I heard Mu'awiyah say on the day of 'Ashura when he was on the Mindar: O people of Al-Madinah, where are your scholars? I heard the Messenger of Allah say on this day: "I am fasting, so whoever wants to fast let him do so."  

سَمِعْتُ مُعَاوِيَةَ يَوْمَ عَاشُورَاءَ وَهُوَ عَلَى الْمِنْبَرِ يَقُولُ يَا أَهْلَ الْمَدِينَةِ أَيْنَ عُلَمَاؤُكُمْ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ فِي هَذَا الْيَوْمِ إِنِّي صَائِمٌ فَمَنْ شَاءَ أَنْ يَصُومَ فَلْيَصُمْ  

[Machine] He heard Muawiyah giving a sermon in Medina, saying, "O people of Medina, where are your scholars? I heard the Messenger of Allah ﷺ saying, 'This is the day of Ashura, and fasting it is not obligatory upon us. So whoever among you wants to fast, let him fast. As for me, I am fasting, and the people are fasting as well."  

أَنَّهُ سَمِعَ مُعَاوِيَةَ يَخْطُبُ بِالْمَدِينَةِ يَقُولُ يَا أَهْلَ الْمَدِينَةِ أَيْنَ عُلَمَاؤُكُمْ؟ سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ هَذَا يَوْمُ عَاشُورَاءَ وَلَمْ يُفْرَضْ عَلَيْنَا صِيَامُهُ فَمَنْ شَاءَ مِنْكُمْ أَنْ يَصُومَ فَلْيَصُمْ فَإِنِّي صَائِمٌ فَصَامَ النَّاسُ  

[Machine] Moawiya gave a speech in Medina during a visit he made on the day of Ashura. He asked, "Where are your scholars, O people of Medina? I heard the Messenger of Allah ﷺ say, 'This is the day of Ashura, and it is not obligatory for you to fast on it, but I am fasting. Whoever wants to fast may do so.'"  

أَنَّ مُعَاوِيَةَ خَطَبَ بِالْمَدِينَةَ فِي قَدْمَةٍ قَدِمَهَا يَوْمَ عَاشُورَاءَ فَقَالَ أَيْنَ عُلَمَاؤُكُمْ يَا أَهْلَ الْمَدِينَةِ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ «هَذَا يَوْمُ عَاشُورَاءَ وَلَمْ يُكْتَبْ عَلَيْكُمْ صِيَامُهُ وَأَنَا صَائِمٌ فَمَنْ أَحَبَّ أَنْ يَصُومَ فَلْيَصُمْ»
