Ruling on stomach acidity which flows from the stomach

Q 6: What is the ruling on stomach acidity which flows from the stomach into the mouth during Sawm (Fast), but returns back to one's stomach?

A: It is Wajib (obligatory) on the fasting person to spit out whatever is regurgitated from the stomach. If one intentionally swallows it, the Sawm is considered invalid, as one willingly allows something to enter their stomach. However, if the acidity reaches one's mouth or is refluxed to the stomach involuntarily, then there is no blame. Allah (Glorified and Exalted be He) says: Allâh burdens not a person beyond his scope. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
