Fidyah
Fidyah is paid by those who are unable to fast owing to illness, old age or infirmity. Fidyah consists of paying £3 for a person per day.
In Ramadan, if a person is unable to fast because he is elderly or sick with no hope of recovery, then he is not obliged to fast. Instead, he should feed one poor person for each day (Fidyah). £3 Per Person Per Day
