It was narrated from Muhammad bin Saifi that the Messenger of Allah (ﷺ) said to us on the Day of ‘Ashura’:

“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.

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا مُحَمَّدُ بْنُ فُضَيْلٍ، عَنْ حُصَيْنٍ، عَنِ الشَّعْبِيِّ، عَنْ مُحَمَّدِ بْنِ صَيْفِيٍّ، قَالَ: قَالَ لَنَا رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ يَوْمَ عَاشُورَاءَ: ‏"‏ مِنْكُمْ أَحَدٌ طَعِمَ الْيَوْمَ؟ ‏"‏ ‏.‏ قُلْنَا: مِنَّا طَعِمَ وَمِنَّا مَنْ لَمْ يَطْعَمْ ‏.‏ قَالَ: ‏"‏ فَأَتِمُّوا بَقِيَّةَ يَوْمِكُمْ. مَنْ كَانَ طَعِمَ وَمَنْ لَمْ يَطْعَمْ. فَأَرْسِلُوا إِلَى أَهْلِ الْعَرُوضِ فَلْيُتِمُّوا بَقِيَّةَ يَوْمِهِمْ ‏"‏ ‏.‏ قَالَ يَعْنِي أَهْلَ الْعَرُوضِ حَوْلَ الْمَدِينَةِ ‏.‏
