Praise be to Allaah.
Firstly:
The majority of Maaliki,
Shaafa’i and Hanbali fuqaha’ are of the view that paying cash does not count
as the fidyah for not fasting, and what must be given is actual food,
because Allaah says (interpretation of the meaning):
“And as for those who
can fast with difficulty, (e.g. an old man), they have (a choice either to
fast or) to feed a Miskeen (poor person) (for every day)”
[al-Baqarah 2:184]
Ibn ‘Abbaas (may Allaah be
pleased with him) said: This refers to old men and old women who cannot
fast, so they should feed one poor person for each day. Narrated by
al-Bukhaari, 4505.
It says in Fataawa
al-Lajnah al-Daa’imah (10/198): If the doctors have stated that this
sickness means that you cannot fast, and there is no hope of recovery, then
you must feed one poor person for each day, giving half a saa’ of the local
staple food, whether it is dates or something else, for past and future
months. If you give a poor person dinner or breakfast for the number of days
that you did not fast, that will be sufficient. As for giving cash, that
does not count. End quote.
So the elderly or sick
person for whom there is no hope of recovery should feed one poor person for
each day, giving half a saa’ of wheat, dates, rice or similar local staple.
That is equivalent to approximately one and a half kilograms. See Fataawa
Ramadaan, p. 545.
He may give it all in one
go at the end of the month, 45 kilograms of rice, for example, or if he
makes some food and invites poor people to come and eat, that is good,
because that is what Anas (may Allaah be pleased with him) did.
Secondly:
If you gave the fidyah in
the form of cash following the view of a scholar who issued a fatwa to that
effect, then you do not have to give it again. But if you did that
yourselves, then you have to give it again, in order to be on the safe side
and in order to honour your father, may Allaah have mercy on hi and forgive
him.
And Allaah knows best.
