whos more important
SalaamuAlikumweRahmetAllaahebarkatuh.
Sorry I do not have the time to search for the exact hadiths, but I am pretty sure InshAllaah that for a man, his mother has more rights over him than his wife (tho of course the wife still has her rights over him and there would be some conditions (for example, the wife requesting their own apartment, dwelling, etc etc instead of living with his family, even if her mother in law refuses, the wife still has that right). For a married woman, her husband has more rights over her than her own family-mother or father. Those who are not married have their parents as their priorities after Allaah SWT of course in any of the cases. I am pretty sure of this but InshAllaah someone can help you with the correct hadith for sound proof. InshAllaah take care.
