Ashura, observed on the 10th day of the Islamic month of Muharram, holds distinct yet overlapping meanings within Islam. For Sunni Muslims, it typically commemorates the day God saved Moses and the Israelites from Pharaoh, and it is often marked by voluntary fasting. For Shiʿa Muslims, however, it is a solemn day of mourning for the martyrdom of Husayn ibn Ali at the Battle of Karbala in 680 CE.
