Hadith text
حَدَّثَنَا أَبُو عَاصِمٍ، عَنْ يَزِيدَ بْنِ أَبِي عُبَيْدٍ، عَنْ سَلَمَةَ بْنِ الأَكْوَعِ ـ رضى الله عنه ـ أَنَّ النَّبِيَّ صلى الله عليه وسلم بَعَثَ رَجُلاً يُنَادِي فِي النَّاسِ، يَوْمَ عَاشُورَاءَ " أَنْ مَنْ أَكَلَ فَلْيُتِمَّ أَوْ فَلْيَصُمْ، وَمَنْ لَمْ يَأْكُلْ فَلاَ يَأْكُلْ ".
Narrated Salama bin Al-Akwa`:Once the Prophet (ﷺ) ordered a person on 'Ashura' (the tenth of Muharram) to announce, "Whoever has eaten, should not eat any more, but fast, and who has not eaten should not eat, but complete his fast (till the end of the day)
Salama bin Al-Akwa bataate hain: Ek baar Nabi ne Ashura (Muharram ki das taareekh) ke din ek shaks ko elaan karne ka hukum diya: "Jisne khaya hai, woh aur na khaye, balki roza rakhe, aur jisne nahi khaya, woh na khaye, balki apna roza poora kare (din ke aakhir tak)."
