مسند امام احمد بن حنبل · کتاب ‹ باب · حديث 5203
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
It was narrated that Ibn 'Umar said: The day of 'Ashoora' was a day on which the people of the jahaliyyah used to fast . When (the command to fast) Ramadaan was revealed, the Messenger of Allah (PBUH) was asked about it and he said: Ashoora' is one of the days of Allah, so whoever wishes may omit it.”
ابْنِ عُمَرَ ← نَافِعٍ ← عُبَيْدِ اللَّهِ ← يَحْيَى
