The matter of divorce is discussed in verse 2:228 of the Qu'ran. The Qu'ran instructs women to wait at least three menstrual periods, called Iddah, before committing to a second marriage. The purpose of the Iddah is to ensure that a woman's pregnancy will be linked to the correct biological father. In the case of a Talāq, which is a divorce initiated by the man, the man is supposed to announce the words "I divorce you" aloud three times, each separated by a three-month waiting period. Certain practices of the Talāq divorce allows the "I divorce you" utterance to be completed in one sitting; however, the concept of "Triple Divorce" in one sitting is considered wrong in some branches of Islam such as with the Shia Muslims. During the three-month waiting period, only the man has the right to initiate a marital reunion if both sides desire to reconcile. This yields a gender equality perspective in the sense that women have power over men in regards to finance parallel to how men have power over women in regards to obedience, both of which are only valid to a reasonable extent. While a Ṭalāq can be completed easily, a divorce that is initiated by the woman, called a Khula, is harder to obtain due to a woman's requirement to repay her dowry and give up child custody. More specifically, a woman is to give up custody of her child if the child is over the age of seven. If a woman gains custody of her child who is under the age of seven, she must still forfeit custody upon the child's seventh birthday. Although the Islamic religion requires the woman to repay her dowry, she is also entitled to receive financial support from her former husband if needed. This cycle of financial matters protects the woman's property from being taken advantage of during or after marriage.
