Arabic (Original)
حَدَّثَنَا يَحْيَى عَنْ عُبَيْدِ اللَّهِ أَخْبَرَنِي نَافِعٌ عَنِ ابْنِ عُمَرَ قَالَ كَانَ يَوْمُ عَاشُورَاءَ يَوْمًا يَصُومُهُ أَهْلُ الْجَاهِلِيَّةِ فَلَمَّا نَزَلَ رَمَضَانُ سُئِلَ عَنْهُ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ هُوَ يَوْمٌ مِنْ أَيَّامِ اللَّهِ تَعَالَى مَنْ شَاءَ صَامَهُ وَمَنْ شَاءَ تَرَكَهُ حَدَّثَنَا رَوْحٌ أَخْبَرَنَا عُبَيْدُ اللَّهِ بْنُ الْأَخْنَسِ أَخْبَرَنِي نَافِعٌ عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ فَذَكَرَ مِثْلَهُ.
English Translation
Yahya narrated to us, from 'Ubayd Allah - Nafi' informed me - from Ibn 'Umar, who said: The day of 'Ashura' was a day that the people of Jahiliyyah used to fast. When Ramadan was revealed, the Messenger of Allah, peace and blessings be upon him, was asked about it. He said: 'It is one of the days of Allah Almighty; whoever wishes may fast it, and whoever wishes may leave it.' Rawh narrated to us: 'Ubayd Allah ibn al-Akhnas informed us - Nafi' informed me, from 'Abd Allah ibn 'Umar, and he mentioned the like of it.
