"O Safwaan! Allah has sworn that one who recites my grandfather's (Imam Husain [as]) ziyaarat from near or afar, and raises his hands to seek his demands after reciting this ziyaarat, shall find Allah fulfilling his demands. Allah, on account of this ziyaarat, shall not let disappointment and dejection befall his servant. Allah will bestow him with nothing less than Paradise andimmunise him from the Fire. His stature shall be elevated manifold, so that he will be bestowed with powers of intercession on the day of mahshar. O Safwaan! Reciting Ziyaarat of Imam Husain (a.s) is equal to Ziyaarat of Allah at the Arsh (throne)."
