Question:
May Allah reward you, Your Eminence, father. The questioner says: If one vows that every time he commits a sin he must fast for a day, is it obligatory for him to fast every time he commits the sin?
Answer:
This is not his intention of drawing near through fasting; his intention is to restrain himself. So it is like an oath. If he breaks it, he owes the expiation for an oath. Yes.
