Muslimpress:Muslims, particularly Shias, mourn the 10thday of Muharram, the first month in lunar calendar, for the unjust martyrdom of Imam Hussein, the 4thImam for Shia Muslims.The celebrations of the Day of Ashura have traditionally included rituals. It is commemorated by Shia Muslims as a day of mourning for the martyrdom of Hussein ibn Ali, the grandson of Muhammad at the Battle of Karbala on 10th of Muharram in the year 61 AH (October 10, 680 CE). The massacre of Hussein with small group of his companions and family members had great impact on the religious conscience of Muslims. Especially Shia Muslims have ever remembered it with sorrow and passion. Mourning for Hussein and his companions began almost immediately after the Battle of Karbala, by his survivor relatives and supporters. Popular elegies were made by poets to commemorate Battle of Karbala during Umayyads and Abbasids era. The earliest public mourning rituals happened in 963 CE during Buyid dynasty. Nowadays, in some countries such as Afghanistan, Iran, Iraq, Lebanon, Bahrain, and Pakistan, the Commemoration of Hussein ibn Ali has become a national holiday and most ethnic and religious communities participate in it. In secular country like India, Ashura (10th day in the month of Muharram) is celebrated and is a public holiday due to the presence of a significant Indian Shia Muslim population.
