If one spouse curses the other, does this mean that they are divorced or forbidden to one another?
Question

                What is the situation of a man if he curses his wife or the wife if she curses her husband? Does one of them become forbidden to the other with regard to marriage?.
Praise be to Allah.
    Neither of them becomes forbidden to the other as the result 
    of cursing, and divorce does not take place as a result, but his cursing her 
    or her cursing him is a major sin, and they have to repent and ask Allaah 
    for forgiveness for what they have done, and they have to ask one another 
    for forgiveness for cursing one another. And Allaah is the Source of 
    strength. May Allaah send blessings and peace upon His Prophet Muhammad and 
    his family and companions. End quote.
