Fasting Rules: Obligations, Exemptions, and Makeup Days

The Obligation of Fasting

Fasting the month of Ramadan is the fourth pillar of Islam, obligatory upon every adult Muslim who is sane, healthy, and resident. Allah (God) says in the Quran: "O you who have believed, decreed upon you is fasting as it was decreed upon those before you, that you may become righteous" (Surah al-Baqarah, 2:183). The fast of Ramadan entails abstaining from food, drink, and sexual relations from the true dawn (fajr sadiq) until sunset, accompanied by the intention to fast for the sake of Allah. It is an act of worship that combines physical discipline with spiritual purification.

Who Is Obligated to Fast?

The scholars of all four madhabs agree that fasting is obligatory upon the Muslim who is adult (has reached puberty), sane, capable, and not traveling. Children who have not yet reached puberty are not obligated, though it is recommended to encourage them gradually. Someone who is insane during Ramadan has no obligation to make up missed days, as the pen is lifted from those who lack mental capacity.

The healthy resident must fast every day of Ramadan. A person who deliberately breaks a fast without a valid excuse has committed a major sin. In the Hanafi and Maliki schools, deliberate breaking of the fast in certain circumstances — specifically intercourse — requires a kaffarah (expiation): freeing a slave, or if that is not possible, fasting sixty consecutive days, or if that is not possible, feeding sixty poor people. The Shafi'i and Hanbali schools require kaffarah only for sexual intercourse, not for eating or drinking intentionally.

Exemptions and Concessions

Islam's mercy is evident in the extensive framework of exemptions. The traveler is permitted to break the fast and make up the missed days later, provided the journey meets the minimum distance (approximately 80 km or 48 miles according to most scholars). The sick person whose illness would be worsened by fasting — or who requires regular medication — may also break the fast and make up the days. Allah says: "And whoever is ill or on a journey — then an equal number of other days" (Quran 2:185).

The pregnant woman and the nursing mother who fear harm to themselves or their child may break the fast. The majority hold that they must make up the missed days; some scholars additionally require them to feed a poor person (fidyah) for each missed day if the reason was fear for the child rather than their own health. The elderly person or chronically ill individual who cannot fast at all and has no hope of recovery is not required to make up the days but must pay fidyah — feeding one poor person for each missed day.

What Invalidates the Fast

The fast is broken by anything that enters the body through a natural passage intentionally: eating, drinking, and sexual intercourse are the primary invalidators. Vomiting intentionally breaks the fast; vomiting involuntarily does not. Smoking breaks the fast according to all contemporary scholarly bodies. Injections are a matter of scholarly debate: the majority hold that intravenous or intramuscular injections of nutrients break the fast, while injections that do not nourish (such as local anesthetics) generally do not. Menstruation and post-childbirth bleeding (nifas) immediately invalidate the fast, obligating the woman to make up those days after Ramadan. The Prophet (PBUH) said: "Whoever forgets that he is fasting and eats or drinks, let him complete his fast, for it is Allah who has fed him and given him drink" (Bukhari). Forgetting, then, is a complete excuse, and the fast remains valid.
