It might be necessary to disown x, in order to protect y and z.
Though in most cases I'd guess that it's just a form of expression, a way of getting out of the mire of arguments/infighting/stress.
I don't condone it, but I've seen enough to know that people have their breaking points and sometimes completely cutting off communication is the only way to get past the anger long enough for reason to return.
**Disowning a family member or blood relative is testament to saying there is no room for forgiveness......both concepts go directly against our religion !
Even if we remove religion from the equation family is family and only family is there to stand beside you at times of difficulty . One cannot isolate oneself from their family , yes there may be differences and even arguments and times of separation to reflect on things but eventually a family always stays together though thick and thin.
Coming to desi society , basic rules of joint family within our culture dictates that even when for some dire reason a member is "Disowned" it is more in the form of limiting social interaction than an outright cutting of ties........**
but what if your kid turns into a male prostitute and runs front page ads for his services? would you still "own" himzz
In Islam we cannot disown anyone ..period so no discussion on that
but if you're child strays you can show narazgi,so that the other person realises he has moral values to follow
and always show love humbleness and a willingness to tolerate and accept,its the best way to make another person realise his mistake
when we talk about disowninga child is NOT allowed in Islam, what we actually say is that that child CAN NOT be excluded from inheritance. the parents still may NOT want to see his their child ever again in his/her life and that's fine, however, it is discouraged to break ties with blood relatives. you may show your disapproval in many other ways.
