Ashura is a day of commemoration in Islam. It occurs annually on the tenth of Muharram, the first month of the Islamic calendar. For Sunni Muslims, Ashura marks the parting of the Red Sea by Moses and the salvation of the Israelites. Also on this day, Noah disembarked from the Ark, God forgave Adam, and Joseph was released from prison, among various other auspicious events on Ashura in Sunni tradition. Ashura is celebrated in Sunni Islam through supererogatory fasting and other acceptable expressions of joy. In some Sunni communities, the annual Ashura festivities include carnivals, bonfires, and special dishes, even though some Sunni scholars have criticized such practices.
