By definition, domestic violence is a pattern of abuse – physical, sexual, financial, spiritual, emotional and verbal, including disparagement, blame, being ostracized, isolated and condemned. Domestic violence can be defined as a pattern of behavior in any relationship that is used to gain or maintain power and control over an intimate partner. Not one incident but a pattern. Men are victims too, 835,000 a year in the US alone, of physical, emotional and financial abuse.
Many cultures think it is the man's God-given right to hit a woman. According to Change from within: Muslim perspectives about Domestic Violence, even the term Domestic Violence is looked upon as suspect by many Muslims because it is reminiscent of “western feminists ideals and doesn't occur in traditional Islamic texts”. Another reason that many do not publicly bring this issue up is because it re-enforces the stereotype that Islam is a violent religion. Others do not want to pry into 'private lives' except to tsk tsk over the plight of another. More Here (Muslim Matters)
