Is it lawful for a father to take from his daughter's Mahr?
Is it permissible for the father or the Waliy (a legally accountable person acting for a woman regarding marriage) of a woman to take from her Mahr (mandatory gift to a bride from her groom)?
It is permissible for her father to take whatever he wants from her Mahr, or other money, by her consent. It is also permissible for him to take from her Mahr in a way that does not cause her loss provided that he does not give it to any of his children. With regards to her Waliy in the marriage contract, it is not permissible for them to take from her money, whether from her Mahr or other money, unless it is she who gives it to him willingly and she is grown-up. Likewise, it is not permissible for guardians, other than the father to take from his daughter's money except by her consent. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
