As children, are we obligated to make up the fasts that our father missed during the War of Liberation, knowing that he made up some of them after the war, or should we offer a ransom instead? And is this making up of fasts restricted to children only?

Whoever dies with an obligatory fast due upon them, either originally or due to a vow, it is permissible for their guardian to fast on their behalf as a supererogatory act. If a number of their guardians fast on their behalf, equaling the number of days due, all on one day, that suffices. The term 'guardian' includes every close relative, or specifically the heir, or the agnates. However, if there is no certainty about an obligatory fast being due upon the deceased, then it is not permissible to fast on their behalf.
