Does a husband's curse pursue his wife forever, and what is its ruling in Islamic law, and what are the consequences for the one who inflicts it and the one upon whom it is inflicted?

Cursing is prohibited, especially between spouses. A curse does not pursue a person forever; if the cursed individual deserves the curse, it falls upon them, but if they do not deserve it, it returns to the one who uttered it. One can be rid of a curse and its effects through sincere repentance, remorse, and seeking forgiveness for the sin, whether from the curser for exceeding what is prohibited, or from the cursed so that the curse does not befall them.
