Praise be to Allaah.
Praise Allaah that your family is closely-knit and that you do not suffer the things that your wife suffers from her family. Appreciating this blessing fully will make you give thanks to your Lord and feel compassion for your wife because of the state of affairs with her family. This will motivate you to console her and stand beside her to ward off mistreatment from her, and boost her morale when she is faced with these attacks. Our advice to your wife is to bear her family’s mistreatment with patience and to strive to call the individuals in her family who are less evil and more open to accepting the truth. Then if her kaafir family are causing her trouble, she can mix with them less, and make her visits to them brief and for a purpose. No Muslim is obliged to mix with kaafir relatives if he cannot bear their mistreatment, but he should strive to bear their mistreatment with patience and call them to Islam.
