Approaching the month of Muharram and the mourning ceremonies on the martyrdom of the master and sovereign of all martyrs [Imam Hussain (a.s.)], the ritual ceremony of clearing dust from the noble tomb of Imam Ali Ibn Musa al-Reza (a.s.) in the holy city of Mashhad was performed on Saturday, with Ayatollah Khamenei, a number of scholars and the various groups of people in attendance. The Leader of the Islamic Revolution has always attended this spiritual ceremony which is held frequently by Astan Quds.
