"The Messenger of Allah said on the day of Ashura: Is there anyone among you who has eaten today?' They said: Some of us are fasting and some of us are not.' He said: 'Do not eat for the rest of the day, and send word to the people of Al-Al-Arud telling them not to eat for the rest of the day."' (Using translation from Nasāʾī 2320)  

الكبرى للنسائي:٢٦٤١أَخْبَرَنَا عَبْدُ اللهِ بْنُ أَحْمَدَ بْنِ عَبْدِ اللهِ بْنِ يُونُسَ قَالَ حَدَّثَنَا عَبْثَرٌ قَالَ حَدَّثَنَا حُصَيْنٌ عَنِ الشَّعْبِيِّ عَنْ مُحَمَّدِ بْنِ صَيْفِيٍّ قَالَ

قَالَ رَسُولُ اللهِ ﷺ يَوْمَ عَاشُورَاءَ «أَمِنْكُمْ أَحَدٌ أَكَلَ الْيَوْمَ؟» فَقَالُوا مِنَّا مَنْ صَامَ وَمِنَّا مَنْ لَمْ يَصُمْ قَالَ «فَأَتِمُّوا بَقِيَّةَ يَوْمِكُمْ وَابْعَثُوا إِلَى أَهْلِ الْعُرُوضِ فَلْيُتِمُّوا بَقِيَّةَ يَوْمِهِمْ»

“Has anyone among you eaten today?” We said: “Some of us have eaten and some of us have not.” He said: “Complete the rest of your day (i.e., do not eat for the rest of the day), whoever has eaten and whoever has not eaten. And send word to the people of the suburbs to complete the rest of their day.” He was referring to the people of the suburbs around Al-Madinah.
