The month of Muharram or Muharram al-Haram is the first month of the Islamic calendar (Hijri) and according to Muslims, it is one of the forbidden months. Before Islam, the name of this month was the conference (in Arabic: Mu'tamir or Al-Mu'tamer) during the Jahili period, and during the Jahili period, Muharram (in Arabic: Al-Muharram) was the name that was called the month of Safar. Muharram is the first month of the twelve lunar months and one of the forbidden months in which war was prohibited during the Jahili period and also in Islam. Of course, this month is very sacred for Shiites; To honor this month, they cry for Hussain bin Ali and perform breast-beating and belay and feed those who go to the belay, because they believe that these things will benefit them after death and their sins will be forgiven.

The first night and day of Muharram, as the first of the lunar year, has special prayers and rituals that are described in the book of Mufatih al-Janan. Muharram is the month of grief and mourning for the Shiites in the murder of Hussain bin Ali.
