"Salamah told us that the Messenger of Allah said to a man: 'Announce the day of Ashura. Whoever has eaten let him not eat for the rest of the day, and whoever has not eaten, let him fast."'  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لِرَجُلٍ أَذِّنْ يَوْمَ عَاشُورَاءَ مَنْ كَانَ أَكَلَ فَلْيُتِمَّ بَقِيَّةَ يَوْمِهِ وَمَنْ لَمْ يَكُنْ أَكَلَ فَلْيَصُمْ  

[Machine] The Prophet (pbuh) sent a man on the day of Ashura who embraced Islam saying, "Indeed, today is the day of Ashura, so whoever has eaten or drank should complete the rest of his day, and whoever has not eaten or drank should observe fasting."  

أَنَّ النَّبِيَّ ﷺ بَعَثَ يَوْمَ عَاشُورَاءَ رَجُلًا مِنْ أَسْلَمَ «إِنَّ الْيَوْمَ يَوْمُ عَاشُورَاءَ فَمَنْ كَانَ أَكَلَ أَوْ شَرِبَ فَلْيُتِمَّ بَقِيَّةَ يَوْمِهِ وَمَنْ لَمْ يَكُنْ أَكَلَ أَوْ شَرِبَ فَلْيَصُمْهُ»  

[Machine] The Messenger of Allah ﷺ sent a man who had embraced Islam to make an announcement among the people, saying, "Today is the day of Ashura. Whoever had eaten should not eat anything else for the remainder of the day, and whoever had not eaten or drunk anything should observe fasting."  

أَنَّ رَسُولَ اللَّهِ ﷺ بَعَثَ رَجُلًا مِنْ أَسْلَمَ يُؤَذِّنُ فِي النَّاسِ «أَنَّ الْيَوْمَ يَوْمُ عَاشُورَاءَ فَمَنْ أَكَلَ فَلَا يَأْكُلْ شَيْئًا بَقِيَّةَ يَوْمِهِ وَمَنْ لَمْ يَكُنْ أَكَلَ أَوْ شَرِبَ فَلْيَصُمْ»  

"Salamah told us that the Messenger of Allah said to a man: 'Announce the day of Ashura. Whoever has eaten let him not eat for the rest of the day, and whoever has not eaten, let him fast."' (Using translation from Nasāʾī 2321)  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ لِرَجُلٍ «أَذِّنْ يَوْمَ عَاشُورَاءَ مَنْ أَكَلَ فَلْيُتِمَّ بَقِيَّةَ يَوْمِهِ وَمَنْ لَمْ يَكُنْ أَكَلَ فَلْيَصُمْ»  

The Prophet ﷺ ordered a man from the tribe of Bani Aslam to announce amongst the people that whoever had eaten should fast the rest of the day, and whoever had not eaten should continue his fast, as that day was the day of 'Ashura' . (Using translation from Bukhārī 2007)   

"أَذِّنْ في النَّاسِ: أَنَّ مَنْ كان أكَلَ فليَصُمْ بقيَّةَ يوْمِه، ومَنْ لم يكنْ أَكَلَ فليَصُمْ، فإِنَّ اليَوْمَ يومُ عاشُوراءَ".  

"مَنْ أَكَلَ مِنْكُمْ يَوْمَ عَاشُورَاءَ فلا بَقيَّةَ يَوْمِه، وَمَنْ لَمْ يَأكُلْ فَليُتِمَّ صَوْمَه".
