How can I ascertain whether my mother-in-law has used sorcery to influence my husband to remain attached to her, especially with the change in his behavior towards me and his preference for his family over me, bearing in mind that she used to deal with makers of amulets?

Accusing someone of sorcery is not permissible except with clear evidence, and mere suspicion is insufficient. A Muslim should consistently recite the Quran and perform remembrances (adhkar) to fortify themselves. Do not accuse your mother-in-law of sorcery. Instead, be kind to her to win her affection, for a righteous wife unites a man with his family. We advise your husband to be good to you, honor your companionship, and consider your feelings, while also fulfilling his duty of kindness to his mother. Your salary is your own, and your husband has no right to take anything from it except with your consent.
