If a person vows to give something in the name of the Most Noble Messenger of Allah (Ṣ), one of the Infallible Imams (ʿA), one of the children of the Infallible Imams (ʿA), or one of the past scholars, etc., then in the event that he intends for it to be spent in a specific manner, he must give it to be spent in that manner.
However, if he does not intend for it to be spent in any specific way, he must give it to be spent on something that is associated with that distinguished personality, such as helping poor visitors to his shrine, or he must give it to be spent on his shrine or in a way that would elevate his name.
