In Twelverism, Nikah mut'ah is a form of marriage. It is also called Sigheh. Unlike Nikāḥ, which is the other form of marriage in Islamic law, a Nikah mut'ah marriage does not last for the two people's whole lives. It lasts only limited time. Nikah mutah is about sexual pleasure.[1] Followers of Twelver Shia Islam believe that Nikah mut'ah is legal, but most other Muslims disagree on this belief.
