Question:
He says: My grandfather made a vow to my sister when she was young. He said, "If she gets married, I will buy her a new car if I am wealthy, and if I am not wealthy, I will buy her a used car." And because my sister got married and he was wealthy, we reminded him of what he had said, so he denied it.
Answer:
In any case, this is a vow of a permissible act. A vow of a permissible act: if you vow that you will buy a car for someone, this is a vow of a permissible act. If you wish, you buy it; if you wish, you expiate it with the expiation of an oath. One who vows to do a permissible act is given the choice between doing it and paying the expiation of an oath. Yes.
