1)If a person became
balag in Zilqidah & zakah is due on him but doesn't remember the date, what
should he do?
2)If for the sake of remembering his annual zakah, can one permanentaly change
his zakah due date to 1st Ramadan from Zilqidah. I.e. he is fixing the zakah
due date a few months earlier than the actual due date?
