Wife serving her husband’s father
Question

                My husband’s father has come to live with us and he is sick with Alzheimer’s which is causing a lot of problems and stress. What are my duties towards him?.
Praise be to Allah.
    The wife is not obliged to serve her husband’s father, mother 
    or any of his relatives; rather it is good manners, if she lives in the same 
    house, to serve his parents. But obliging her to do that is not permissible. 
    So it is not permissible for her husband to force her to do that, and it is 
    not obligatory for her. What I advocate is that the wife should be patient 
    in serving her husband’s father and remember that it will not harm her, 
    rather it will make her more respected and loved by her husband. And Allah 
    is the Source of strength. End quote.
