Mut'a: Temporary marriage.
Useful information: The Arabic dictionaries define mut'a as 'enjoyment, pleasure, delight'. The root form, m-t: signifies, 'to carry away, to take away'. A 'marriage of mut'a' is a marriage which the contract stipulates will last for a fixed period of time. This 'marriage of mut'a' is referred to both in the hadith literature and, in much more detail, in the books on jurisprudence (fiqh ). In the hadith and in other sayings related from early Muslims the word 'mut'a' itself is usually employed. The Shi'is hold that this particular term is the preferred name for temporary marriage because the Qur'an itself refers to this kind of marriage employing a term derived from the same root. In the following verse, the word istimta', the tenth verbal form of the root m-t-', is translated as 'enjoy': 'So those of them [women] whom you enjoy, give to them their appointed wages' (4:24).
