Muarram (Arabic: muarram) is the first month of the Islamic calendar. It is one of the four sacred months of the year. It is held to be the holiest month, Ramadan coming after. The word "Muharram" means "forbidden". Since the Islamic calendar is a lunar calendar, Muharram moves from year to year when compared with the Gregorian calendar.
The tenth day of Muharram is known as the Day of Ashura, part of the Mourning of Muharram for Shia Muslims and a day of fasting for Sunni Muslims. The practice of fasting during Ashura stems from the hadith that Musa (Moses) and his people obtained a victory over the Egyptian Pharaoh on the 10th day of Muharram; accordingly Muhammad asked Muslims to fast on this day and on the day prior, the Day of Tasu'a.
