Shiite pilgrims from Syria and abroad used to flock to the Sayyida Zeinab shrine outside of Damascus every year to commemorate Ashoura, a solemn day marking the 7th-century martyrdom of the Prophet Muhammad’s grandson. In the days leading up to Ashoura, the streets would be lined with black and red mourning banners and funeral tents. On the day of the commemoration, black-clad mourners would process through the streets, while in gathering halls known as “husseiniyas,” the faithful would listen and weep as clerics recounted the death of Imam Hussein and his 72 companions in the battle of Karbala in present-day Iraq.
