Tasua is the 9th day of Muharram and the day before Ashura . This day is devoted to Abbas ibn Ali because of his bravery as the great general of Hussein's army. Abbas symbolizes a figure of manliness, chivalry and loyalty in Shia culture.
Millions of black-clad mourners have been holding ceremonies across Iran as well as Iraq, Pakistan, Azerbaijan Republic and Lebanon. Mourning processions will also be held in Europe, America and Africa later in the day.
During Muharram, Iranian people across the country traditionally cook and distribute Nazri (charity food) among their neighbors, family and the poor. Free food is also offered to people who participate in the mourning ceremonies.
They mark the anniversary of the martyrdom of Imam Hussein and 72 of his companions, who fell in a battle for justice against the second Umayyad caliph, Yazid I, in the Iraqi city of Karbala some 14 centuries ago.
Imam Hussein and his companions were martyred on Ashura, the tenth day of Muharram, which falls on November 4 this year.
Muharram ceremonies symbolize the eternal and unwavering stance of truth against falsehood and humanity’s struggle against tyranny, the cause for which Imam Hussein was martyred.
