Allamah Mirza Husain Noori (may Allah exalt his position) quotes in his book ‘Darus Salaam’ from his teacher Haj Fath Ali Sultanabadi that he said: It was my routine that whenever I heard about the death of a follower (Shi’ah) of Ahlulbait (a.s.), whether known or unknown to me, I recited Namaz e Wahshat, and this was not known to anyone else except myself.
One day I met one of my friends who told me that the previous night he saw in a dream a Shi’ah who had died some days ago. My friend asked him as to how his state was. He replied that he was in deep trouble facing the consequences of his deeds, till one so and so (he took my name) person recited Namaz for him.
He said that, “May Allah bless his father, he rescued me from severe chastisement.” My friend asked me regarding the Namaz and I had to tell him.
