How can one deal with a situation where a woman supplicates against an oppressed person using adhkar (remembrances of Allah), and what is the solution to confront this harm?

If a man has wronged a woman, he should seek her forgiveness. If he has not wronged her, then what has befallen him may be due to envy or a sin. If the woman has bewitched him, then refer to the fatwas regarding the cure for magic. And beware of going to charlatans and soothsayers.
