Making up missed fasts becomes a vital concern for individuals who realise they unknowingly engaged in actions that invalidated their worship during the month of Ramadan. Many Muslims, particularly those who are self-taught or raised in environments with limited access to formal Islamic education, may inadvertently commit acts that break their fast. When a person later discovers the correct Islamic rulings, they naturally seek to rectify their past mistakes and ensure their religious obligations are completely fulfilled.
Repentance from Prohibited Habits
Sometimes, individuals may struggle with prohibited private habits—such as intentional self-stimulation—without fully realising that such actions are not only sinful but also completely invalidate the fast. The initial and most crucial step for anyone who has fallen into such practices is to seek sincere repentance (tawbah). Prominent scholars state that a believer must earnestly ask Allah to accept their repentance and to make their steps firm upon righteousness and piety. It is absolutely imperative that the individual completely abandons the harmful habit and resolves never to return to it.
Allah warmly welcomes the repentance of those who turn back to Him, as stated in the Quran:
“O you who have believed, repent to Allah with sincere repentance. Perhaps your Lord will remove from you your misdeeds and admit you into gardens beneath which rivers flow” (Surah At-Tahrim, 66:8).
Compensating for Past Ramadans
A critical question arises regarding whether past ignorance exempts a person from the duty of compensating for those lost days of fasting. Scholars clarify that when a fast is broken by such deliberate physical actions, the fast is definitively invalidated. Even if the individual acted out of genuine ignorance regarding the specific rules of Ramadan, the fundamental obligation of the missed days is not erased.
Therefore, an individual is still legally required to estimate the number of days they broke in previous years and make up for them. This ruling aligns with the foundational Quranic injunction regarding incomplete obligatory fasts, where Allah commands that missed days must be compensated:
…then an equal number of other days” (Surah Al-Baqarah, 2:184).
A Muslim must diligently calculate these days and observe them to clear their spiritual record and fulfill their binding duty to the Almighty.
