Of the several prescribed Ziyarat of Imam al-Husain, one was recited by one of Infallible Imams, probably Imam al-Mahdi, and reached us through one of his four special deputies. For that reason, it is known as the Ziyarat that was issued from the sacred side (Ziyarat al-Nahiya al-Muqaddasa). One of the most important features of this Ziyarat is that in different phrases, Imam al-Mahdi graphically describes the events of Ashura and the agony that Imam al-Husain and his family faced on that horrific and ominous day.
