Is it required to fast consecutively when making up missed fasts?
● It is preferable to fast consecutively when making up missed fasts if they were missed due to a valid excuse.
● However, if the fasts were missed without a valid excuse, then fasting consecutively is obligatory, because making up the missed fasts in this case must be done immediately.
Separating the makeup fasts goes against the obligation of immediacy, but if someone does so, their fasts will still be valid. However, they will be sinful for delaying without a valid reason.
