Re: Behaviour of the Wife
I think you sound really immature.
You cannot compare his wife to his mother - that’s foolish because his mother gave birth to him and his wife didn’t. You cannot divorce your mother. You’re responsible for her well being no matter who or how she is. That’s it.
In this case, it seems as if the OP’s mother is a bit older and just needs some basic concern. People do this stuff all the time for distant relatives and its not a big deal! Taking them somewhere or holding their bags. You could do this for a neighbor without thinking twice about it. If she was demanding haat ki roti three times a day and going on shopping trips on her son’s credit card while her DIL starved, I see the injustice. But this isn’t injustice. This is common courtesy and if you cannot extend it then you lack compassion for your fellow human beings.
He cannot make her live with his mother according to Islam, you’re right. But Islam doesn’t allow anyone to misuse the rules. If you’re having words with your husband just because you want to finish your morning chai and weren’t able to enjoy it leisurely please don’t be surprised if your MIL turns into Monster in Law soon after.
