[Machine] The day of Ashura was a day that the Quraysh used to observe fasting during the time of ignorance. When Islam came, the Messenger of Allah ﷺ said, "Whoever wishes to fast, he may do so, and whoever wishes to leave it, he may do so."
كَانَ يَوْمُ عَاشُورَاءَ يَوْمًا تَصُومُهُ قُرَيْشٌ فِي الْجَاهِلِيَّةِ فَلَمَّا جَاءَ الْإِسْلَامُ قَالَ رَسُولُ اللهِ ﷺ 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.
أَنَّ يَوْمَ عَاشُورَاءَ كَانَ يُصَامُ فِي الْجَاهِلِيَّةِ فَلَمَّا جَاءَ الإِسْلاَمُ مَنْ شَاءَ صَامَهُ وَمَنْ شَاءَ تَرَكَهُ
