Nikah Mut'ah is a temporary marriage contract in Islamic law, primarily recognized by Shia Muslims. It allows a man and a woman to marry for a specified period, which can range from a few hours to several years, with a predetermined dowry. This type of marriage is often used to fulfill emotional or physical needs without the long-term commitment of a traditional marriage. The practice of Nikah Mut'ah is controversial and not accepted by Sunni Muslims, who view it as inconsistent with the principles of permanent marriage. Supporters argue that it provides a legitimate way to address certain social and personal circumstances, while critics believe it undermines the sanctity of marriage.
