What is the ruling on a wife who raises her voice, argues, lies, tries to separate her husband from his family, and leaves the house without his permission?

It is not permissible to accuse your wife without clear proof, as this is a grave matter in the sight of Allah. Contraceptive pills are not a legitimate or common barrier to pregnancy, and you should not cling to them as evidence for your claim. Therefore, mend your relationship with your wife, fear Allah, and do not let Satan sow doubts. Your wife should obey you in what is good, not raise her voice, and be kind to your family, for rights are reciprocal. Both of you should strive to keep the relationship good for the happiness of your marital life.
