Does a woman's request for divorce from her husband in a moment of anger nullify the marriage?

A wife's mere request for divorce from her husband does not invalidate the marriage, and divorce does not occur unless the husband responds to her and divorces her, unless the husband's anger reaches a point where he loses consciousness and awareness, in which case the divorce does not occur. It is not permissible for the wife to ask her husband for a divorce without a legitimate Shar'i reason.
