أَخْبَرَنَا أَبُو عَاصِمٍ ، عَنْ يَزِيدَ بْنِ أَبِي عُبَيْدٍ ، عَنْ سَلَمَةَ بْنِ الْأَكْوَعِ ، أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بَعَثَ يَوْمَ عَاشُورَاءَ رَجُلًا مِنْ أَسْلَمَ : " إِنَّالْيَوْمَ يَوْمُ عَاشُورَاءَ، فَمَنْ كَانَ أَكَلَ أَوْ شَرِبَ، فَلْيُتِمَّ بَقِيَّةَ يَوْمِهِ، وَمَنْ لَمْ يَكُنْ أَكَلَ أَوْ شَرِبَ، فَلْيَصُمْهُ "

Abu Asim informed us, on the authority of Yazid ibn Abi Ubaid, on the authority of Salamah ibn al-Akwa’, that the Prophet, may God bless him and grant him peace, was sent on the day of Ashura A Muslim man said: “Today is the day of Ashura, so whoever has eaten or drank, let him complete the rest of his day, and whoever has not eaten or drank, let him complete the rest of his day. Let him fast on it.”
