It is one of Allah’s commands to men that they have to treat their spouse well if they are getting divorced or are divorced. (Quran, al-Baqara 2:229, 231). Who mistreats women has exceeded one of Allah’s borders (Khudud-Allah). Exceeding Allah’s borders is a great sin. A man also cannot prevent his divorced former spouse from marrying another man (al-Baqara 2:232).
