Kaffarah for delayed Qaza Sowm (Fast)

If the believer is not able to fast during the blessed month of Ramadan for a legal excuse, he must pay a ransom of 750 grams to the poor, of wheat or rice, or its amount, and he does not have to make it up. If he is able to fast, he pays the ransom, which is 3 British pounds per day or 4 US dollars, and the fasting must be made. Also, we are ready to use the ransom in our project.
