[Machine] The Messenger of Allah ﷺ said, "Indeed, we used to observe fasting on the day of Ashura during the time of ignorance. Then Allah obligated upon us the fasting of Ramadan and He abandoned for us the fasting of Ashura. So whoever wants can fast it, and whoever wants can break their fast."  

الطبراني:١٦٩١٧حَدَّثَنَا بَكْرُ بْنُ سَهْلٍ الدِّمْيَاطِيُّ ثنا شُعَيْبُ بْنُ يَحْيَى ثنا عَبْدُ الْجَبَّارِ بْنُ عُمَرَ عَنِ ابْنِ شِهَابٍ عَنْ عُمَرَ بْنِ عَبْدِ الْعَزِيزِ عَنْ إِبْرَاهِيمَ بْنِ عَبْدِ اللهِ بْنِ قَارِظٍ قَالَ سَمِعْتُ مُعَاوِيَةَ بْنَ أَبِي سُفْيَانَ عَلَى الْمِنْبَرِ وَذَكَرَ يَوْمَ عَاشُورَاءَ فَقَالَ
