Ziyarat Ashura
Ziyarat-e-Ashura is a sacred tradition (Hadees-e-Qudsi) whose references can be found in Misbah al-Mutahajjid by Shaykh al-Tusi and Kamil al-Ziyarat by Ibn Qulawayh.
In expressing veneration and seeking higher levels of peace for Imam Husain (AS), we are trying to unite with his ideas, thoughts and towering volition, and in cursing his opponents who overtly declared themselves to be muslims and believers, but were extensions of hypocrites, we are trying to flee from all their ideas, thoughts and actions. Hence this recital of Ziyarat Ashura seeks to unite the reciter with the sacred spirit of Imam Husain (AS)
