وحَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ ، حَدَّثَنَا لَيْثٌ . ح وحَدَّثَنَا ابْنُ رُمْحٍ ، أَخْبَرَنَا اللَّيْثُ ، عَنْ نَافِعٍ ، عَنِ ابْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا ، أَنَّهُ ذُكِرَ عِنْدَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَوْمُ عَاشُورَاءَ ، فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : " كَانَ يَوْمًا يَصُومُهُ أَهْلُ الْجَاهِلِيَّةِ ، فَمَنْ أَحَبَّ مِنْكُمْ أَنْ يَصُومَهُ فَلْيَصُمْهُ ، وَمَنْ كَرِهَ فَلْيَدَعْهُ " .
Ibn 'Umar (RA) said that the day of 'Ashura was mentioned before the Messenger of Allah (ﷺ) (may peace he upon him). Thereupon the Messenger of Allah, (ﷺ) said: That was a day on which the people of pre-Islamic days used to observe fast. So he who amongst you likes to observe fast should do so, and he who does not like it should abandon it.
