How can one deal with the wife's family that causes problems, and how can one build social relationships for the children despite the distance from the family?

The Sharia encourages harmony and affection among Muslims, especially among relatives whose ties Allah has commanded to be maintained and whose severance He has forbidden. We recommend praying to Allah to rectify the situation, offering advice to relatives and reminding them of Allah and His mercy, and involving wise individuals to mediate between them. Furthermore, do not allow family problems to affect your relationship with your wife, and exercise patience and remembrance (dhikr) to overcome this trial. Moreover, what has happened should not prevent your wife from communicating with righteous women and upright families, as this provides support in enduring hardships.
