A Father's Relationship to His Children After Marriage
Question :
What are the Islamic regulations regarding the relation between parents and their married children? Please explain, because parents' intrusion in the affairs of their child's family often leads in discord.
Answer:
The relationship between parents and their children after marriage is one of duty and devotion. Thus the child must be dutiful to his parents before and after he is married. Meanwhile, the parents must be good to their children since they are among their kin and nurturing ties among them is obligatory. So it is not allowed for them to harm their children by creating problems between their son and his wife. If the son sees no other choice, if he thinks it impossible to live with them, he can live in another home, while still fulfilling his duties as a faithful son.
