Question:
The questioner says: If a Muslim vows that if he falls into a specific sin, he will fast for a full year, and he did fall into it, is he required to fast this year?
Answer:
This is not intended as an act of drawing near to Allah; rather, it is intended to prevent himself from falling into the sin. It follows the course of an oath, and he expiates it with the expiation for an oath. Yes.
