Praise be to Allaah.
What
is meant by feeding (a poor person) is half a saa’ of the staple
food of the country, such as dates, wheat, etc. This is equivalent to approximately
one and a half kilograms of rice. See
Question # 9985.
With
regard to giving the price of the food instead of the food itself, the correct
view is that giving the price does not fulfil the conditions of the kafaarah
(expiation). This is the view of the majority of scholars. Ibn Qudaamah said
in al-Mughni: “The kafaarah is not achieved by paying the
price of the food or clothing, because Allaah mentioned giving food, so the
kafaarah is not achieved by anything else. Allaah gives us the choice
of three things’ if it were permissible to give the price, the choice
would not have been limited to these three…” (al-Mughni by
Ibn Qudaamah, 11/256)
