Re: Your Father and MIL are having an illicit affair!
That is allowed in Islam, btw. What KS is talking about is having an illicit affair. They are two diff things. Lets not compare Adultery with Nikah.
The man already has a wife and the woman is a widow. Do you think they married just like that, ofcourse it started with an affair (if not illicit) under their kids noses.
