People who cannot fast or break their fasts during Ramadan should perform qada fasts. In the Qur’an, the following is stated: “If any of you is so ill that he cannot fast, or on a journey, he must fast the same number of other days.” (the Qur’an, al-Baqarah, 2:184). There is no recorded decree about qada fasts to be performed on end. For this reason, qada fasts might be performed on end or on separate days except for the days that it is makrooh to fast. However, it is best to perform these qada fasts as soon as possible.
