Criteria for Obligation: Fasting is mandatory for every Muslim who is sane, has reached puberty, is physically capable, and is not traveling. Those who do not meet these criteria are either temporarily or permanently excused from the practice.
Qada (Making Up Fasts): Individuals with temporary excuses—such as travelers, those with short-term illnesses, or women during menstruation—must make up the missed days later. This is a one-for-one replacement () that should ideally be completed before the next Ramadan.
Fidyah (Compensation): For those who are permanently unable to fast due to old age or chronic, incurable illness, the requirement is replaced by Fidyah. This involves providing a meal to a person in need for every day of fasting that is missed.
Nullifiers vs. Accidental Acts: A fast is only broken if a person eats, drinks, or engages in prohibited acts intentionally. If a person eats or drinks out of forgetfulness, the fast remains valid, and they should continue fasting as soon as they remember.
Classification of Fasts: Not all fasts carry the same legal weight. Fasts are categorized based on their timing and the nature of the obligation.
| Category | Example | Ruling |
|---|---|---|
| Fard (Obligatory) | Ramadan | Mandatory for all eligible adults |
| Sunnah (Recommended) | Day of Arafah, Mondays/Thursdays | Highly rewarded but not required |
| Haram (Forbidden) | Days of Eid (Fitr and Adha) | Prohibited to fast on these days |
| Makruh (Disliked) | Fasting only on a Friday | Discouraged unless part of a sequence |
Identify the Requirement: When analyzing scenarios, first determine if the individual meets the conditions of obligation (sanity, puberty, health, residency). If any condition is missing, the fast is not mandatory.
Distinguish Qada from Fidyah: Always check if the reason for missing the fast is temporary or permanent. Temporary reasons require Qada (repayment in days), while permanent reasons require Fidyah (repayment in charity/food).
Verify the Timing of Niyyah: Remember that for the obligatory Ramadan fast, the intention must be established before dawn. For voluntary fasts, many schools of thought allow the intention to be made later in the morning, provided no nullifiers have occurred.
Common Misconception Check: Swallowing saliva, using a toothbrush (without swallowing paste), or accidental eating do not invalidate the fast. Focus on 'intentionality' as the deciding factor.
