In Shi'a Islam, examples of mourning practices are held annually in the month of Muharram, the first month of Islamic Lunar calendar. This mourning is held in the commemoration of Imam Al Husayn ibn Ali, who was martyred along with his 72 companions by Yazid bin Muawiyah. Shi'a Muslims wear black clothes and take out processions on road to mourn on the tragedy of Karbala. Shi'a Muslims also mourn the death of Fatima (the only daughter of Muhammad) and the Shi'a Imams.
