If wife leaves before the expiry of the term fixed for muta, the husband is entitled to deduct

In a muta (temporary) marriage under Ithna Ashari (Shia) law, if the marriage is consummated, the wife is entitled to the whole dower if the full term is completed or if the husband ends the cohabitation early; however, if the wife voluntarily leaves the husband before the expiry of the fixed term, the husband is entitled to deduct "a proportionate part of the dower" corresponding to the unexpired portion of the term.
