What should we do about the marriage bond, my brother's changed circumstances, and the continuous problems at home after discovering previous acts of magic and talismans, and should we trust a female شيخة who asks for money for treatment?

We advise maintaining the morning and evening remembrances (adhkar) and seeking refuge (ta'awwudhat) from evil, as well as before sleeping, and adhering to religious obligations such as wearing the hijab and abandoning sins. If you suspect sorcery, you can perform ruqyah yourselves or seek assistance from ruqyah practitioners who follow the Sunnah. The suspected amulet (hijab), bag, and papers should be destroyed and buried outside the house while reciting the refuge-seeking supplications. To achieve marriage, seek the help of your mahrams to propose marriage to righteous young men, and get to know righteous women.
