Is it obligatory to feed 80 indigents after making up 28 days out of 80 days that were not observed? Is it permissible to give the expiation in cash to a family or individual without informing them of the reason, prior to completing the make-up days?

Feeding as an expiation for delaying the making up of Ramadan is for the days that were delayed until another Ramadan, for one who was capable and aware of the prohibition, and not for all the days of the year. The expiation is not repeated with repeated delays. It is permissible to offer expiation before, during, or after making up the fast. The original form of expiation is feeding, and it is not permissible to give it in cash according to most scholars. It is advised to fear Allah and avoid excessive questioning in response to whisperings.
