Imam used to arrange a ceremony where preachers used to speak about the sufferings of Karbala and Imam Khomeini obliged himself to sit from the beginning to end and used to shed tears in remembrance of Ashura.
It has been reported that Imam was bound to perform prayers and recite specific supplications on these important days of mourning, especially on the day of Ashura.
Imam Khomeini had great devotion towards Ahl al-Bayt (Holy Prophet’s Household) and even used to cry loudly when events of Karbala and Ashura were mentioned.
