This hadith is listed as number 2639 in Maktaba Shamila
حَدَّثَنِي حَدَّثَنِي عَمْرٌو النَّاقِدُ ، حَدَّثَنَا سُفْيَانُ ، عَنِ الزُّهْرِيِّ ، عَنْ عُرْوَةَ ، عَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا : " أَنَّ يَوْمَ عَاشُورَاءَ كَانَ يُصَامُ فِي الْجَاهِلِيَّةِ ، فَلَمَّا جَاءَ الْإِسْلَامُ ، مَنْ شَاءَ صَامَهُ ، وَمَنْ شَاءَ تَرَكَهُ " .
'A'isha (Allah be pleased with her) reported. In the pre-Islamic days fast was observed on the day of Ashura, but with the advent of Islam (its position was ascertained as that of a voluntary fast). Then he who wished to fast fasted, and he who liked to abandon it abandoned it.
