Fasting on the day of Aashoora (10th Muharram)

Re: Fasting on the day of Aashoora (10th Muharram)

Prophet’s saying and act is ‘muqqaddam’ over any event that comes after. When and which tragedy was celebrated annually in the time of Prophet SAW? Nobody has given an answer to me on that. If we can are ordered to celebrate Eid al Azha to remember Ibrahim AS’s obidience of Allah, why its strange to celebrate Musa AS’s remarkable history changing event. Prophet’s SAW order is order, we don’t need to disect it if its Jewish tradition. You forget that it is Musa AS’s miracle by the grace of Allah that they celebrated, not the wonders or deeds of Jewish people.
