[Machine] The Messenger of Allah ﷺ said on the day of Ashura, "Whoever among you has consumed anything, let him refrain from eating the rest of the day, and whoever hasn't, let him fast." He also sent a message to the people of Arudh and commanded them to fast as well.
أَنَّ رَسُولَ اللهِ ﷺ قَالَ يَوْمَ عَاشُورَاءَ «مَنْ كَانَ مِنْكُمْ طَعِمَ فَلْيُمْسِكْ بَقِيَّةَ يَوْمِهِ وَمَنْ لَمْ يَكُنْ طَعِمَ فَلْيَصُمْ» وَأَرْسَلَ إِلَى أَهْلِ الْعَرُوضِ فَأَمَرَهُمْ بِصَوْمِهِ
