Fidya - If a person cannot fast due to ill health or old age, then they must give compensation for each day missed, with the intention that if they ever are to become healthy again then they have to keep qada.

If he is poor then he should ask Allah for forgiveness for not being able to fast.

Those unable to fast for this reason must pay £5 (2 meals) for each missed fast to a poor person.

The Prophet (SAW) said “He who feeds a fasting person will gain the same reward as he will, without decreasing from the fasting person’s rewards” Ahmad.
