Paying Mahr proper to that paid to a girl of the same social status

Q 1: I married one of my daughters to a man whom I did not ask to pay a Mahr (mandatory gift to a bride from her groom). One year after their marriage my son-in-law gave me a Toyota (car) though I did not ask him to do so. What is the ruling on this?

A: It is permissible for you to take the car from your son-in-law. If he gave it to you as a Mahr, it should go to your daughter. However, if he gave it to you as a gift; you may take it for yourself but your son-in-law has to pay a proper Mahr to your daughter if he did not do so at the time of the conclusion of the marriage contract. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
