The Hindu law describes -- not prescribes -- eight types of marriages including Gandharva Vivaha. Of these, only four types, namely, Brahmana (giving the girl to an educated bridegroom without dowry), Daiva (giving the girl to a priest during the performance of religious ceremony), Arsha (giving the girl after receiving dowry from the bridegroom) Prajapathya (giving the girl with respect and blessing, without dowry, the groom applies for the hand of the bride) were considered proper for all. The other four, Gandharva (Union of man and woman out of mutual love and consent, independently on their own), Asurika (marrying a girl against her will, by giving wealth to her family and kinsmen), Rakshasa (abducting a girl and marrying her forcibly) Pisacha (stealthily seducing a sleeping, intoxicated or mentally ill girl) were regarded as improper for all. According to shastras, noble marriages had no monetary or business transactions. In Islam, Nikāḥ al-Mutʿah is a type of marriage used in Twelver Shia Islam, where the duration of the marriage and the dowry must be specified and agreed upon in advance. It is a private contract made in a verbal or written format. At the end of the contract, the marriage ends and the wife must undergo iddah (a period of abstinence from sexual intercourse, usually the length of two menstrual cycles). The iddah is intended to give certain paternity to a child should the wife become pregnant during the contract.
