If you don’t fast for any of the days of Ramadan, you’ll be required to pay a charitable form of compensation. You must pay fidya (fidyah) for fasts missed out of necessity, that cannot be made up afterwards.
£5 fidya for each missed fast. This should provide one person with two meals or two people with one meal. However, if someone misses all the fasts of Ramadan, they would need to pay £150.
