I just wanted to ask this we know there are many adhkars and duas read in the morning and evening for protection, can one still be affected by jadoo or nazar when the person does all the adhkars and duas regularly? Also as far as the shiekh story, I am sure he would be reading duas for protection, how come he was affected by jadoo? Normally muwazzatain cured our beloved Prophet SAW from jadoo, then how come one gets afflicted by such nazar or jadoo when a person has the habit of reciting these things?
Also whats the cure for jinn nazar?
