Does one who faints during the day in Ramadan break his fast?

Question : This questioner says: Muhammad 'Abd Allah. If a person faints during the day in Ramadan, is that day counted as a valid fast for him, or is he required to make it up? May Allah reward you.

Answer : Praise be to Allah, Lord of the worlds, and I send prayers and peace upon our Prophet Muhammad, and upon his family and his Companions, and upon those who follow them in excellence until the Day of Judgment. If the one who fainted during the day in Ramadan was conscious for part of the day, then his fast is valid. As for if he was not conscious for any part of the day, then the most cautious course is for him to make up his fast. This is different from the prayer, for if a person faints, he is not required to make up the prayer unless he fainted due to something he did, such as choosing to undergo anesthesia, in which case he is required to make it up.
