Prophet ﷺ came to Medina and saw the Jews fasting on the day of Ashura. He ﷺ asked them about that.
They replied, "This is a good day, the day on which Allah rescued Bani Israel from their enemy. So Moses fasted this day."
Prophet ﷺ said, "We have more claim over Moses than you."
So the Prophet fasted on that day and ordered the Muslims to fast on that day.
[Bukhari 2004]
