AQR hoists black flag over the shrine’s dome as sign of mourning for Imam Hussein (AS)

According to an old tradition, the mourning bodies of Mashhad start covering the religious centers with black fabrics on the last Friday of the month of Dhu al-Hajjah, but the beginning of Muharram in Mashhad becomes official by changing the flag of the dome of Imam Reza (AS) holy shrine.
