Quick answer: Allah exempts several people from fasting: the traveller and the temporarily sick make up the days later (qaza); those permanently unable, such as the frail elderly and the chronically ill, pay fidya instead. Women do not fast during menstruation or post-natal bleeding and make those days up later.
Fasting Ramadan is an obligation, but it is an obligation with built-in mercy. Allah says in Surah Al-Baqarah (2:184–185) that whoever among you is ill or on a journey should fast the same number of days later, and that Allah intends ease for you, not hardship. The exemptions are therefore not loopholes for the lazy; they are part of the law itself, and taking a valid exemption when you need it is obedience, not failure.
The key distinction running through every case is whether the inability is temporary or permanent. Temporary inability — a journey, a short illness, menstruation — leads to qaza: the same number of days made up later. Permanent inability — where there is no realistic hope of ever fasting — leads to fidya: feeding a poor person for each day instead of fasting.
A traveller may break the fast and make the days up later. Scholars have differed on the minimum journey distance, with classical opinions commonly linked to roughly 80–90 kilometres (the distance of qasr prayer), while some contemporary scholars emphasise genuine travel hardship rather than a fixed figure. Short, easy modern journeys are an area of difference; the concession is clearest where travel involves real hardship, and the Prophet (peace be upon him) sometimes fasted while travelling and sometimes not.
Temporary sickness works the same way: if fasting would worsen your illness, delay recovery, or cause genuine harm — not merely mild discomfort — you break the fast and make the days up when well. A trustworthy Muslim doctor's advice carries weight here. If the illness is one-off, like flu or a stomach bug, the answer is simply qaza after Ramadan, spread out as you wish before the next Ramadan.
A person whose illness is chronic or long-term, with no realistic expectation of recovery that would allow making up fasts — for example, someone whose fasting is medically dangerous on an ongoing basis — does not owe qaza. Instead they pay fidya: feeding one poor person for each missed day. The same applies to the very elderly person who cannot fast at all, or for whom fasting would cause severe hardship and harm.
If an elderly or chronically ill person's condition genuinely improves so that fasting becomes possible, scholars advise acting on the new reality from that point; past fidya already given in good faith is charity and is not clawed back. Because medical situations are individual, for your personal situation, consult a qualified local scholar alongside your doctor before deciding between qaza and fidya.
A pregnant or breastfeeding woman who fears harm for herself or her baby may break the fast. This is established in the teaching of the Prophet (peace be upon him) that Allah has lifted fasting from the pregnant and breastfeeding woman who fears for her child. What she owes afterwards is where scholars differ, and both positions are held by major schools and early authorities.
One well-known view, held by many scholars, is that she makes up the days with qaza only, like the temporarily sick person. Another well-known view, reported from companions such as Ibn Abbas and Ibn Umar, is that she pays fidya, particularly where the concern was for the child. A third position combines both — qaza plus fidya — held by scholars who see her case as resembling both the sick person and the one unable to fast.
Given this genuine difference, a woman should follow the school or scholar she trusts, ideally deciding before Ramadan so the month is free of anxiety. What is not in dispute: she must not fast if there is a real risk of harm to herself or her baby, and no one should pressure her to do so.
A woman does not fast while menstruating or during post-natal bleeding (nifas), even if the bleeding starts minutes before Maghrib. Unlike the pregnancy case, there is no difference of opinion here: she makes the days up later as qaza, and fidya is not applicable to these days at all. Aisha (may Allah be pleased with her) reported that women in the Prophet's time were commanded to make up the fasts but not the prayers.
Children are not obliged to fast until puberty. Parents are encouraged to train children gradually — part-day fasts, praise and involvement at sehri and iftar — without imposing hardship. A person with mental incapacity that removes legal responsibility is not obliged to fast; where the condition is permanent, families often give fidya on related guidance from scholars, and where it is temporary, the case is judged by its details.
Use this summary as a starting point, not a fatwa. If two categories seem to apply to you, or your health is involved, speak to a qualified scholar and your doctor before Ramadan begins.
Classical scholars commonly linked the exemption to the journey distance at which prayers are shortened, roughly 80–90 kilometres, while some contemporary scholars focus on whether the travel genuinely involves hardship. Easy, short modern journeys are an area of difference. If your journey is long or difficult, the concession clearly applies; for borderline cases, ask a qualified local scholar.
If your illness is ongoing and there is no realistic prospect of you being able to make up fasts in the future, you pay fidya — feeding one poor person per day — instead of qaza. If you might recover or have periods where fasting is possible, qaza applies. Get medical advice first, then confirm with a scholar who knows your situation.
Scholars differ on this in a well-known way. Many hold qaza only, treating her like the temporarily sick. Others hold fidya, especially where the fear was for the baby, and a third view combines qaza and fidya. Follow the position of the school or qualified scholar you trust, and never fast where there is a real risk of harm.
No. Days missed because of menstruation or post-natal bleeding are made up with qaza only, by scholarly consensus, and fidya is not a substitute for them. Fidya is only for those permanently unable to fast, such as the chronically ill and the frail elderly who cannot make days up later.
Fasting becomes obligatory at puberty. Before that, it is recommended to train children gradually with partial or full fasts as they are able, with encouragement rather than pressure. If a child is struggling, unwell or too young, there is no blame at all — the obligation simply has not begun for them yet.
