Question

Question: The second wife of my sister’s husband had such a powerful spell performed to cause separation between my sister and her husband that, according to the practitioners of incantations, if it is turned back, the life of the woman who had it performed will be in danger. In such a case, is it permitted by the Shari‘a to turn back the spell?

Let it be turned back by such a practitioner who will nullify the effect of this spell without committing kufr, shirk or anything haram, and without taking a life or causing destruction.
