Muharram is one of the stupidest months in Islamic countries specially Shiite countries. It’s full of sadness and mourning. In wiki Muharram defines as:
The first day of Muharram is the start of the Islamic Year. The Remembrance of Muharram takes place during this month. The Shia Muslims celebrate in a different way in which they commemorate the Battle of Karbala and consider this a month of sadness and mourning. The commemoration reaches its climax on the tenth day of Muharram, known as Ashurah.
Muharram (Arabic: محرم) is the first month of the Islamic calendar. It is one of the four sanctified months of the year. Fighting in this month is looked down upon and is sometimes put to the side in respect for Islam. Since the Islamic calendar is lunar, Muharram moves from year to year when compared with the Gregorian calendar.
This is the day Husayn ibn Ali, the grandson of Muhammad, was killed along with his family members and friends in the Battle of Karbala. This day is also important in other religions. For example, it is related to the Jews as being the time when Moses crossed the Red Sea while escaping from Pharaoh. Sunni Muslims often fast on this sacred day.
The month of Muharram also has traditions which have no support from Islamic teachings. For example, the elebration of the Muslim new year, and the partying and card giving, etc, associated with it is considered to be a bidah and even haraam to all Shia muslims because they feel it is a time to mourn and it is haraam to express any happiness.
Well, Amir Normandi designed controversial Muharram's postcards which they back to February 2006. I didn't get the chance to see them before so I thought it could be interesting to you too.
