Millions of Muslims around the world are commemorating Tasu'a, the 9th day of the lunar calendar month of Muharram, ahead of the day that witnessed the martyrdom of the third Shia Imam al-Hussein Bin Ali [AS].

Iran Press/Middle East: Tasu'a precedes Ashura on the 10th day of Muharram, when Imam Hussein [AS], a grandson of Islam’s Prophet Muhammad [PBUH], and his 72 companions were martyred in the Battle of Karbala, in southern Iraq, in 680 AD after fighting courageously for justice against the much larger army of the Umayyad caliph, Yazid I.

Tasu'a known as the Day of Loyalty and Resistance is devoted to Abbas ibn Ali, Imam Hussein’s half-brother, who made great sacrifices during the battle.

He was martyred as he tried to bring water for women and children in the Imam's camp, who had no water to drink for days due to a siege by the enemy.
