Mishnayos Yevamos Perek 15 Mishnah 7

The mishna discusses a similar case. If a woman said: My husband died and afterward my father-in-law died, she may marry and take her marriage contract, and it is prohibited for her mother-in-law to remarry, as a woman may not testify on behalf of her mother-in-law. If the mother-in-law was the daughter of an Israelite married to a priest, she may partake of teruma; this is the statement of Rabbi Tarfon. Rabbi Akiva says: This is not the way to spare her from transgression; there is no remedy unless it is prohibited for the mother-in-law to marry and also prohibited for her to partake of teruma. In relation to the dispute between Rabbi Tarfon and Rabbi Akiva in the previous mishna, in which Rabbi Akiva states that one must avoid a possible transgression, the mishna cites two similar cases involving other topics. With regard to one who betrothed one of five women, and he does not know which of them he betrothed, and each one of them says: He betrothed me, if he does not want to marry any of them he gives a bill of divorce to each and every one of them so none will have the status of a woman with regard to whom there is uncertainty whether she is divorced. And he leaves the marriage contract among them and departs. The marriage contract remains in dispute between the women until they clarify which of them is entitled to the money. This is the statement of Rabbi Tarfon. Rabbi Akiva says: This is not the way to spare someone from transgression, as perhaps the woman he actually betrothed will not receive the money to which she is entitled. There is no remedy unless he gives a bill of divorce and a marriage contract payment to each and every one. And likewise, in the case of one who stole money from one of five people and does not know from which of them he stole, and each one says: He stole from me, he leaves the stolen money among them and departs, and they will decide among themselves how to distribute the money; this is the statement of Rabbi Tarfon. Rabbi Akiva says: This is not the way to spare him from transgression; there is no remedy unless he pays each and every one of them.
