Is it permissible to undo a spell that causes marital delay and disfigurement using the the same method through which it was cast, or not?

Magic is a reality, and its effect is tangible. It can only be undone by seeking help from Allah the Almighty through supplication, remembrances (dhikr), and lawful incantations (ruqya), while maintaining good thoughts about Him. However, undoing it with similar magic or seeking help from sorcerers and diviners is an act of polytheism (shirk).

The "tasfeeh" magic for girls is a type of binding performed by some mothers, which prevents intercourse. The way to remove it is through lawful incantations, maintaining remembrances, and reciting the Quran. If the location of the magic is known, and it is extracted and nullified, that is among the most beneficial treatments.

Some people might imagine magic to be the cause of their stalled affairs, while it is merely an illusion. The treatment for magic is with the Holy Quran, by reciting verses such as Ayat al-Kursi and the Mu'awwidhat (Surahs Al-Falaq and An-Nas) over the person affected by magic, or by reciting them into water for the person to drink and bathe with.

It is recommended to persist in obedience to Allah and His remembrance, to seek His help, to have good thoughts about Him, to be patient, and to turn to Him frequently with supplication and humility.
