falling into what is forbidden. Now that it has already occurred, you must do the following: make up every day you missed, repent, and feel genuine remorse for what you have done. In addition, for the days of the first Ramadan you skipped you must feed one needy person for each day, giving half a sāʿ (roughly 1.5 kg) of staple food per day. As for the subsequent Ramadan, you are only required to make up the days you missed without any feeding. Allah knows best.
Question: Must he make up the missed fasts immediately, before the next Ramadan arrives?
Answer: Yes. He is required to do so before the coming Ramadan. He may not allow the new Ramadan to begin while he still owes fasts from the previous one, so far as he is able.

Question: I was in one of the Arab countries and came here for work. Ramadan began and I had no money at all, so I felt compelled to break the fast and keep working. Do I incur any liability for that?
Answer: Employment does not make it permissible to break the fast in Ramadan. The concession to break the fast is granted only to the sick, the traveller, a menstruating woman, a pregnant or nursing woman who fears harm for her child or for herself, and the extremely elderly person who cannot fast. These are the people who may lawfully break the fast; if they are later able, they must make up the missed days, and if they are unable, they must feed the poor in their stead. As for the labourer, his work does not entitle him to break the fast. He must work and fast, and if the job is incompatible with fasting he should quit that job and look for another that suits fasting; there are plenty of jobs available.
In short: a worker who is resident and not travelling is not allowed to break the fast.
