I have an uninvited sister-in-law who came to our house without me agreeing and it’s been more than 10 years now and she is bad mouthed and a fabricator, she has been brainwashing my wife and interferring in other relatives lives and is being supported by her mother. My question is what does Islam says about this category of guests who are destroying my family and home and is also ungrateful?
This is very sad that we have these type of people in our chain of relatives who spoil our relations. The Quran says:
They should be advised not to do indulge is slandering and destroying relations and if they must continue, you should make sure to avoid them.
Allah knows best
