Arabic (Original)
قَالَ حَدَّثَنَا حَمَّادُ بْنُ مَسْعَدَةَ عَنْ يَزِيدَ يَعْنِي ابْنَ أَبِي عُبَيْدٍ عَنْ سَلَمَةَ بْنِ الْأَكْوَعِ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَمَرَ رَجُلًا مِنْ أَسْلَمَ أَنْ يُؤَذِّنَ فِي النَّاسِ يَوْمَ عَاشُورَاءَ مَنْ كَانَ صَائِمًا فَلْيُتِمَّ صَوْمَهُ وَمَنْ كَانَ أَكَلَ فَلَا يَأْكُلْ شَيْئًا وَلِيُتِمَّ صَوْمَهُ.
English Translation
He said: Hammad ibn Mas'adah narrated to us, from Yazid - meaning Ibn Abi 'Ubayd - from Salamah ibn al-Akwa', that the Prophet, peace and blessings be upon him, ordered a man from Aslam to announce among the people on the day of 'Ashura': "Whoever is fasting should complete his fast, and whoever has eaten should not eat anything [more] and should complete his fast."
