If I live till the next (year), I would definitely observe fast on the 9th, and the narration transmitted by Abu Bakr is:" He meant the day of Ashura."
قَالَ رَسُولُ اللَّهِ ﷺ لَئِنْ بَقِيتُ إِلَى قَابِلٍ لأَصُومَنَّ التَّاسِعَ وَفِي رِوَايَةِ أَبِي بَكْرٍ قَالَ يَعْنِي يَوْمَ عَاشُورَاءَ
Messenger of Allah, it is a day which the Jews and Christians hold in high esteem. Thereupon the Messenger of Allah ﷺ said: When the next year comes, God willing, we would observe fast on the 9th But the Messenger of Allah ﷺ died before the advent of the next year.
حِينَ صَامَ رَسُولُ اللَّهِ ﷺ يَوْمَ عَاشُورَاءَ وَأَمَرَ بِصِيَامِهِ قَالُوا يَا رَسُولَ اللَّهِ إِنَّهُ يَوْمٌ تُعَظِّمُهُ الْيَهُودُ وَالنَّصَارَى فَقَالَ رَسُولُ اللَّهِ ﷺ فَإِذَا كَانَ الْعَامُ الْمُقْبِلُ إِنْ شَاءَ اللَّهُ صُمْنَا الْيَوْمَ التَّاسِعَ قَالَ فَلَمْ يَأْتِ الْعَامُ الْمُقْبِلُ حَتَّى تُوُفِّيَ رَسُولُ اللَّهِ ﷺ
