It is generally known that no days are equivalent to the days of Ramadan except the days of another Ramadan. At the same time, all days of Ramadan are originally fast days, so that one can never make up for the missed fast days of Ramadan during another Ramadan. Abu Hurairah (may Allah be pleased with him) reported that the Prophet (peace and blessings be upon him) said, “Whoever breaks a single day of Ramadan fast without valid reason will not be able to make up for the same by fasting an entire year” (Ahmad and An-Nasa’i).
Concerning the legal excuses that allow one not to observe the fast of Ramadan, Allah, Exalted be He, says: (And whoever of you is sick or on a journey, (let him fast the same) number of other days; He desireth not hardship for you) (Al-Baqarah 2:185). Sickness referred to in this verse that is considered a legal excuse for not observing the fast of Ramadan is that which occurs, becomes urgent, or is aggravated as a result of fasting.
Sheikh Ahmad Kutty, a senior lecturer and Islamic scholar at the Islamic Institute of Toronto, Ontario, Canada, states the following: It is my understanding that the timings for the pills are not inflexible, as people have a tendency to forget or skip a day altogether.
Nevertheless, every Muslim lady should speak to their doctor or pharmacist about delaying the timing of taking the pill and continuing on a post- iftar or pre- sahur schedule until the end of Ramadan [that is, after breaking the fast at sunset or before dawn].
It is important for us to remember that fasting of Ramadan is a fundamental religious obligation that we ought to observe unless we have genuine reasons to skip it. The Prophet (peace and blessings be upon him) said, “Whoever breaks a single day of Ramadan fast without valid reason will not be able to make up for the same by fasting an entire year” (Ahmad and An-Nasa’i).
May Allah grant us steadfastness in obedience to Him and may He accept our fasts, prayers, and good works. Ameen.
