in his discourse about the visitation (ziyara) of al-Husayn (AS) on the day of 'Ashura', be it from near or far, said, 'Then let him mourn for al-Husayn (AS) and weep over him, and let him enjoin weeping for him on others in his house who are not in a state of dissimulation, and they should condole with each other for their bereavement of al-Husayn (AS). ... I [i.e. the narrator] asked, 'How should they condole with each other?' to which he replied, 'They should say: may Allah make our reward great for our bereavement of al-Husayn, and place us and you among those who avenge his blood with his representative, the Imam Mahdi from the family of Muhammad, peace be upon them.'
