Is it permissible for my wife to prevent my daughter from visiting my mother, fearing sorcery, knowing that my mother has a history with sorcery?

It is not permissible to accuse a Muslim of sorcery without proof. If it is definitively proven that the wife's mother practiced sorcery, then she must be advised and urged to repent. If she does not repent, the wife may abandon her and prevent her daughter from visiting her, if that deters her and prompts her to repent, and this is confirmed if the wife fears for herself or her daughter from the harm of sorcery. The mother's right to her son's filial piety remains, and this is not forfeited by practicing sorcery. Connection is not limited to visits; it includes asking, calling, fulfilling needs, and meeting outside her home. Connection has degrees, and one who does not reach its utmost is not considered a severer of ties. Abandonment for more than three days is permissible for one who fears that associating [with the person] will corrupt his religion or his worldly affairs.
