Is the marriage valid if a woman says that she breastfed the husband and the husband's father, but she does not remember when that happened?

If the woman is trustworthy and remembers that five breastfeedings occurred, then the marriage is void, and you must separate from her. The children will be attributed to you due to the doubt [of the marriage's validity]. However, if there is doubt about her truthfulness or the number of breastfeedings, then the prohibition is not established, but it is preferable to separate from her as a precaution. It is advisable to consult trustworthy scholars to clarify the number of breastfeedings.
