Under Muslim Law, during the term of a "Muta Marriage":

Under Shia Muslim Law, a Muta (temporary) marriage is contracted for a fixed period and dissolves ipso facto upon the expiry of that term or upon the death of either party. Neither the husband nor the wife has a right of divorce (talaq) in a Muta marriage, although the husband may terminate the contract before the expiry of the fixed period by making a gift of the unexpired term (Hiba-i-Muddat) to the wife.
