Question:
He says: Honorable Shaykh, may Allah grant you success, if a person fasts one day and breaks the fast the next day, it may happen that he fasts on a Friday or a Saturday alone. Is this permissible?
Answer:
Yes, because he did not intend to fast on Friday or Saturday; he did not intend this, but rather his day of fasting coincided with Friday and Saturday without intention, so there is no harm.
