و حَدَّثَنَا أَبُو بَکْرِ بْنُ أَبِي شَيْبَةَ وَأَبُو کُرَيْبٍ قَالَا حَدَّثَنَا ابْنُ نُمَيْرٍ عَنْ هِشَامٍ بِهَذَا الْإِسْنَادِ وَلَمْ يَذْکُرْ فِي أَوَّلِ الْحَدِيثِ وَکَانَ رَسُولُ اللَّهِ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ يَصُومُهُ وَقَالَ فِي آخِرِ الْحَدِيثِ وَتَرَکَ عَاشُورَائَ فَمَنْ شَائَ صَامَهُ وَمَنْ شَائَ تَرَکَهُ وَلَمْ يَجْعَلْهُ مِنْ قَوْلِ النَّبِيِّ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ کَرِوَايَةِ جَرِيرٍ
صحیح مسلم · Hadith 2638
A'isha (Allah be pleased with her) reported that the Quraish used to fast on the day of 'Ashura in the pre-Islamic days and the Messenger of Allah ( صلی اللہ علیہ وسلم ) also observed it. When he migrated to Medina, he himself observed this fast and commanded (others) to observe it. But when fasting during the month of Ramadan was made obligatory he said: He who wishes to observe this fast may do so, and he who wishes to abandon it may do so.
