What is the ruling on one who says, “If I wear such-and-such a garment, then I owe such-and-such”?

Question : And he began to fast. Does this mean in this fast of his? Of course, it has become so. Or, or, or, or that

Answer : And in the matter of if he says, “If I do such-and-such, then I owe him that I will fast such-and-such,” or “If I succeed, then I owe him that I will fast,” but if he says, “If I succeed, then I owe him that I will fast,” this is obedience, because it is gratitude for a blessing, and gratitude for a blessing is among obedience, yes? As for the permissible, he said to him, “I have vowed to wear this garment.” This is permissible. We say you are at your option: if you wish, wear the garment, and if you wish, do not wear it, and you owe the expiation for the garment. But in the second case, regarding the conditional permissible, such as if he says, “If I wear this garment, then I have no vow to fast ten days,” this also has the ruling of an oath. Did you understand?
So now, if he wears the garment, he must fulfill it. And if he does not wear it, it is not required. So if he fasts in this case, we say he is rewarded for this fast because he fulfilled his vow, just as a person is rewarded if he swears an oath and then expiates for it.
