Respected Hazrat G, Assalamo  Alaikum!  I want to tell you about my experience. I did this process for many years.  I was afraid from the wild animal specially the dogs . I was read in the book if the dog, the wild animal or the lion are come opposite to you just read the  “یمعشر الجن و الانس ان استطعتم  Yamashar aljini walinsi wa in stzatm”

Incident:  Once I was coming to home near 8’o clock of winter nights. I was passing from the narrow street suddenly a dog came there it was ferocity. I started to recite the same aiyat due to blessing if this aiyatLikewise if you are afraid of the ferocity of any human beings just focus that person and read this Aiyat  inshAllah you will be safe from his wrong attentions.
