Ashura is the tenth day of Muharram, which is the first month in the Lunar calendar. On that day, Husayn, the third Imam of Shia Muslims and the grandson of Prophet Muhammad, was martyred in the Battle of Karbala. Ashura is also a part of an important religious and national gathering that takes place every year in Muharram in Iran. #iran #muharram #ashura #irantour
