Paying more than the amount due of Zakat-ul-Fitr

A: The amount to be paid for Zakatul-Fitr per a person is one Sa` equal to that of the Prophet (peace be upon him) which equals about three kilograms. Accordingly, the amount you paid on behalf of the family mentioned above, 90 kilograms, is enough and the increase is considered a charity.May Allah grant us success. Mau blessings and peace be upon our Prophet Muhammad, his family and Companions!
