A woman claims to have breastfed a child, and the child's mother denies it; whose word is to be acted upon?

Question:
A woman claims to have breastfed a child, and the child's mother denies it. Yes, a woman claimed that she breastfed a child, but the child's mother denies it. She denies it. So, does the son have the right to enter the home of the wet nurse and her daughters, and be a mahram (a relative one may not marry) to them?

Answer:
If the woman reporting the breastfeeding is a trustworthy woman, a trustworthy woman, then the breastfeeding is established by the testimony of one trustworthy woman. As for the one who denies it, her denial is not relied upon, because the one who affirms takes precedence over the one who denies. The one who denies may forget, may forget, whereas the one who affirms has knowledge of the matter. So, the issue with the woman reporting it is that if she is trustworthy and pious, the breastfeeding is established even if the mother denies it, because the one who affirms takes precedence over the one who denies. This is a legal principle.
