Is it Haram to raise your voice in an argument with your husband? If so is it a major or a minor sin?
Shaikh Adel As-Sayed:
This depends on her intention. If she raised her voice just because she is frustrated or nervous, but if her husband reminded her that her voice is loud she retracts and lowers her voice, then she is not sinful.
But if she raised her voice aiming at insulting him, on purpose, then yes she is sinful and it is a major sin.
Note of Zaynab El-Kateb:
The Quran describes this act by النشوز in chapter An-Nisaa verse 34
Meaning when the wife is rebellious, and treating her husband as if she is higher than him. The word in Arabic نشوز comes from “higher place”.
