حَدَّثَنَا أَبُو کُرَيْبٍ حَدَّثَنَا أَبُو أُسَامَةَ عَنْ الْوَلِيدِ يَعْنِي ابْنَ کَثِيرٍ حَدَّثَنِي نَافِعٌ أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا حَدَّثَهُ أَنَّهُ سَمِعَ رَسُولَ اللَّهِ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ فِي يَوْمِ عَاشُورَائَ إِنَّ هَذَا يَوْمٌ کَانَ يَصُومُهُ أَهْلُ الْجَاهِلِيَّةِ فَمَنْ أَحَبَّ أَنْ يَصُومَهُ فَلْيَصُمْهُ وَمَنْ أَحَبَّ أَنْ يَتْرُکَهُ فَلْيَتْرُکْهُ وَکَانَ عَبْدُ اللَّهِ رَضِيَ اللَّهُ عَنْهُ لَا يَصُومُهُ إِلَّا أَنْ يُوَافِقَ صِيَامَهُ
صحیح مسلم · Hadith 2645
Ibn 'Umar (Allah be pleased with them) said that the day of 'Ashura was mentioned before the Messenger of Allah (may peace he upon him). Thereupon the Messenger of Allah, ( صلی اللہ علیہ وسلم ) 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.
