Fidyah
Missing a single fast of Ramadan without a valid Shar’i reason is completely unlawful (Haraam). It is a Shar’i obligation on such a person to repent from this sin and to make up (do Qada) for it. Similarly, the person who did not fast due to a Shar’i excuse, it is also obligatory for him to make up for these fasts after the excuse has terminated. However, if he has reached the stage of Shaykh Faani, i.e. he has become so old that due to old age he does not have the strength to fast and neither does he have any hope of regaining the strength to fast in the future, in fact, his weakness is increasing daily, then in such a case, he must pay Fidyah in exchange for each fast. The Fidyah of one fast is equivalent to one Sadaqah Fitr, i.e. Half a Saa’ (1.92kg) of wheat or its flour, or one Saa’ of (3.84kg) of dates, dry raisins, or barley or its flour.
