Islamic rulling on hurmat - e - musaharat

First of all, it is necessary to understand the Islamic ruling in this matter:

If a man touches his daughter-in-law in such a way that there is no barrier between their bodies, or there is a barrier but the body heat is felt through it, and he also feels sexual desire, or he touches or kisses a part of the body where desire is usually involved without a barrier, then in this case Hurmat-e-Musaharat (marital prohibition) is established. As a result, the daughter-in-law becomes permanently unlawful (haram) for her husband.

Therefore, if the father-in-law touched his daughter-in-law without any barrier and with desire, and the husband confirms his wife's statement, then the woman has become permanently unlawful for her husband. In such a case, it becomes necessary for the husband to separate from her by giving divorce.

However, if the father-in-law touched her over clothing in such a way that body heat was not felt, or the husband does not confirm this claim, then Hurmat-e-Musaharat will not be established.

Now, regarding your specific situation, some important points:

This ruling is very sensitive and serious, so a decision cannot be made based on doubt or general assumptions. The full details must be clear (how the touching happened, whether there was desire, etc.).

If Hurmat-e-Musaharat is truly established, then the ruling is strict. But if the conditions are not fulfilled, then the marriage remains valid.

It is necessary for you to:

Consult a qualified Mufti or a reliable Darul Ifta directly

Gently ask your wife for complete details

Avoid making a rushed decision

As for your relationship with your father:

If he has actually done something wrong, your anger is natural

But completely cutting off ties is not encouraged in Islam

You can maintain a limited and careful relationship while keeping distance.
