2668. If a person makes a vow that he will give Sadaqa to a particular poor, he cannot give it to another poor, and if that poor person dies, he should on the basis of recommended precaution, give the Sadaqa to his heirs.
2669. If a person makes a vow that he will perform the Ziyarat of a particular holy Imam, for example of Abu Abdillah Imam Husayn (A.S.) his going for the Ziyarat of another Imam will not be sufficient, and if he cannot perform the Ziyarat of that particular Imam because of any good excuse, nothing is obligatory on him.
2670. If a person has made a vow that he will go for Ziyarat, but has not included in his vow that he will do Ghusl or pray after the Ziyarat, it is not necessary for him to perform those acts.
2671. If a person makes a vow that he would spend some amount of money on the shrine of one of the Imams, or the descendants of the Imams, without having any particular project in mind, he should spend it on the repairs, lighting, carpeting etc. of the shrine.
2672. If a person makes a vow to use something in the name of Holy Imam himself, and has an intention to put it to a specific use, he should spend it for that very purpose.
2673. If someone makes a vow that he would give a sheep as Sadaqa, or in the name of a Holy Imam, and if it gives milk, or gives birth to a young one, before it is put to use in accordance with the vow, the milk or the lamb will be the property of the person who made the vow, unless he had included them in his vow. And the growth of fat on the animal will be considered part of the vow.
2674. If a person makes a vow for an act, if a patient recovers or a traveller returns home, and if it transpires later that the patient had already recovered or the traveller had already returned before he had made the vow, it will not be necessary for him to fulfil his vow.
2675. If a father or a mother makes a vow that he/she will marry their daughter to a Sayyid, the option rests with the girl when she attains the age of puberty, and the vow made by the parents has no significance.
2676. When a person makes a covenant with Allah, that if his particular lawful need is fulfilled, he will perform a good act, it is necessary for him to fulfil the covenant. Similarly, if he makes a covenant without having any wish, that he will perform a good act, the performing of that act becomes obligatory upon him.
2677. As in the case of vow, a formal declaration should be pronounced in the case of covenant ('Ahd) as well. And it is commonly held that the covenant that one makes should be related to either acts of worship, like, obligatory or Mustahab prayers, or to acts whose performance is better than its renunciation. But this is not so. In fact, all covenants which fall within the category specified in rule no. 2680 related to oaths, are valid and ought to be fulfilled.
2678. If a person does not act according to the covenant made by him, he should give a Kaffarah for it, i.e. he should either feed sixty poor persons, or fast consecutively for two months, or set free a slave.
