In the Name of Allah, the All-Merciful, the Mercy-Giving

 

All praise is due to Allah. Peace and blessings be upon His Messenger Muhammad.

 

I think both of you need to sort such things out amicably if you want to continue the marriage. Marriage is all about mutual respect and trust. Communication is essential for developing mutual trust.

 

Your mother in law was not wrong in telling you that her daughter- your husband’s sister – would be coming over and staying with you for a few days.

 

Even a good friend could make such requests; so how could you say that his mother does not have the same right. Put yourself in her shoes; what would you think if you were in her place and your daughter in life took objection to that.

 

Having said this, your husband is also wrong in telling you that he does not need to inform you of his sister’s visit.

 

It seems you have been at the throats of each other by not communicating.

 

If you have had a problem with your sister-in-law’s behavior in the past, you should have discussed the issue with your husband and he should be the one to resolve the issue. He should tell his sister to act responsibly.

 

You may do well to see a marriage counselor to sort our marriage problems.

 

Almighty Allah knows best.
