Today, I've watched a video on Youtube regarding common martial issues and got to know that the origin of those marital problems is in the concept of "Joint Family" -(which you will see in the sub-continent), most of the time 2 scenarios are happening in the joint families, either the in-laws are wrong and evildoer or the wives are the evil persons in making of those chaoses in the family. And it is totally unacceptable -the habit of living together under the same roof ; and in those family a man marries a woman and she is bound to act like a servant of his family and this is not islam -- these are things I've learnt so far from the video (made by a renowned Sheikh).
My question is, what would be the perfect flawless family format, in what structure the family should construct in, if the sons start living separately then whom the parents will live with? Or who will take care of them, you know what I mean. So please provide me with an eloquent elaborate answer of this matter with authentic evidences.
Thanks in Advance! Jazakallah!
