Nikah mut‘ah
（重定向自Mutah）
Nikāḥ al-mutʿah (Arabic:نكاح المتعة, literally "temporary marriage"), is a type of marriage permitted 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. A declaration of the intent to marry and an acceptance of the terms are required (as they are in nikah). Nikah mut'ah was also practiced by the pre-Islamic Arabs.
