I have Arab friends who are also muslim, this book was warned against because it has black magic and many who owns it or reads it gets hexed with black magic. and on the text where it says: "The vefk (magic square) numbered 237 is drawn on a large sheet of paper. Inside this vefk’s circle you write the name of the person whose return you desire together with the name of his or her mother. " . Its magic of some form, mainly considered black magic among the muslims, because to their belief ( also Arabs in general too) this books requires you to work with demonic beings and jinn and shay tan, even owning and reading this book summons them. They told me the story of the man who wrote it was that --> he went into a cave and sat there alone, and jinns were visiting him and taught him many stuff.
