To send back or take back; to refute or respond. In Islamic law, it most often refers to taking back a repudiated wife. A new contract or dowry is not necessary as long as the radd takes place during the prescribed waiting period. Radd al-mahr is the return of a dowry by a woman in exchange for a divorce. The term also refers to a response to a complaint in a civil case, and to the act of returning products in a sales contract.
