Wife pardons Mahr under duress

If the husband forces and pressurizes his wife continuously to forgive the Mahr that is due to her, and as a result of not being able to withstand his continuous demands and harassment, she unwillingly and unhappily forgives him, then she is entitled to claim it back at a later stage. The same ruling will apply if he threatens to injure or harm her in some way, and in order to protect herself from the harm, she forgives him unhappily, then she may claim back her Mahr at a later stage.

ALLAH TA’ALA KNOW BEST!
