How do we protect ourselves from a sorceress whose sorcery is transmitted by greeting her?

Question:
May Allah reward you. This questioner says: Honorable Shaykh, I know a woman who is close to my husband’s family who practices sorcery, she practices sorcery, and may Allah protect us from it. She uses it against her face such that when we begin to greet her, it transfers to us. The question is: How do we protect ourselves from this woman, and she is from the family?

Answer:
This is not permissible to leave alone. The authorities must be informed about her so that she is taken and the necessary action is taken against her. Because if it is established that a sorcerer is a sorcerer, he is executed, and he is not left to corrupt society. As for greeting her, if it is known that this is contagious, one does not greet her, out of caution, out of prudence, out of prevention. But this is not sufficient. If there is an authority that enforces the hudud (fixed Qur'anic punishments), it is necessary to inform them, to inform the authority so they look into her case. Yes.
