The Ruling on the Sick Person Fasting | Shaykh Aḥmad ibn Yaḥyá al-Najmī Raḥimahullāh
[Q]: Is the sick person who doesn’t experience any difficulty [while fasting] and fasting doesn’t harm him exempted from fasting?
[A]: If the sick doesn’t experience any difficulty while fasting and fasting doesn’t increase his sickness, then he should fast.
