How does one deal with husband’s parents who have been caught doing black magic on daughter in-law? I want to know because its not forgiveable but how does one treat them? Can the son distance himself from such parents? Caught and accepted it.
Let someone advise them in kindness to repent and renew their Shahada as they have committed one of the enormities that consist in unbelief (kufr). Find it in your heart to forgive them the way the Prophet (saws) left Labid b. al-A`sam in peace even after he became certain he had done that to him. As for your last question the answer is yes in light of the hadith لا يُلْسَعُ المُؤْمِنُ مِن جُحْرٍ مَرَّتِيْنِ “The believer is not bitten from the same hole twice.” As for yourself, take up the Awrad of morning and evening and observe all your obligations towards Allah. He is your protector in dunya and akhira and nothing and no one can interfere with that.
