باب ما جاء فى صوم رسول الله صلى الله عليه وسلمChapter: What has been reported concerning the fasting of the Messenger of Allah (ﷺ)
Ashura fast was initially obligatory
Hadith 308
حَدَّثَنَا هَارُونُ بْنُ إِسْحَاقَ الْهَمْدَانِيُّ قَالَ: حَدَّثَنَا عَبْدَةُ بْنُ سُلَيْمَانَ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، قَالَتْ : «كَانَ عَاشُورَاءُ يَوْمًا تَصُومُهُ قُرَيْشٌ فِي الْجَاهِلِيَّةِ، وَكَانَ رَسُولُ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ يَصُومُهُ، فَلَمَّا قَدِمَ الْمَدِينَةَ صَامَهُ وَأَمَرَ بِصِيَامِهِ، فَلَمَّا افْتُرِضَ رَمَضَانُ كَانَ رَمَضَانُ هُوَ الْفَرِيضَةُ وَتُرِكَ عَاشُورَاءُ، فَمَنْ شَاءَ صَامَهُ وَمَنْ شَاءَ تَرَكَهُ»
It is narrated from Umm al-Mu'mineen Sayyidah Aisha (may Allah be pleased with her), she says: The Quraysh used to fast on the day of Ashura during the period of ignorance, and likewise, the Messenger of Allah (peace and blessings be upon him) also used to fast on this day. Then, when he came to Madinah Munawwarah, he himself fasted on this day and ordered the people to fast as well. Then, when the fasting of Ramadan was made obligatory, only the fasts of Ramadan remained as obligatory, and the fast of Ashura was abandoned. Whoever wished, fasted on this day, and whoever wished, left it.
