Breastfeeding that Prohibits Marriage

Question:
I married a woman after a period during which her mother told me that my father’s or my mother’s sister had breastfed her. The wet nurse has passed away, and I heard nothing from her. I did not know after the marriage that breastfeeding on the man’s side prohibits marriage. Now I have two sons and two daughters, and no one witnessed this breastfeeding except her mother, and she does not know the number of breastfeedings?

Answer:
If her mother does not know the number of breastfeedings, whether it is two, three, or four, nothing is established based on her testimony, and no action is taken on it until she is certain that it is five breastfeedings or more, and until she is also just, a just and trustworthy woman.
As for if she is suspected, and there is enmity between you and her, no action is taken on her testimony. So the result is that there is a concern regarding this woman.
The wife’s mother, if she testifies to breastfeeding, there is a concern regarding it; because she may love the separation of her daughter, she may be angry at the husband, she may want him to separate from her daughter, and she testifies to the breastfeeding. So the result is, if she does not have a precise record of the breastfeeding, praise be to Allah, no action is taken on it.
