Should a woman make Kaffarah for divorcing her husband?

Q 1: When a woman divorces her husband, is she required to make Kaffarah (expiation)? If so, what is it?

A: When a woman pronounces the divorce word to her husband, the divorce does not take place. No Kaffarah is required, but she has to perform Tawbah (repentance to Allah) and ask Allah's forgiveness. Her pronouncement of divorce to her husband goes against the Shari`ah (Islamic law) proof that indicates that the right of divorce is given to the husband or the Islamically lawful authorized person that replaces the husband in divorce. May Allah grant us success. May peace and blessings of Allah be upon our Prophet Muhammad, his family and Companions.
