Does the marriage of a man who married a woman become void if it is proven that her maternal grandmother breastfed him for a full year with light milk, when she was old and her husband had been dead for a long time?

What is prohibited by lineage is also prohibited by suckling. So, if the wife's grandmother (mother's mother) suckles a man five times or more, this man becomes the wife's maternal uncle (her mother's brother). A sister's daughter is prohibited by both lineage and suckling. The old woman becomes this husband's foster mother through suckling. She can suckle even if she is not married, as long as her milk is nourishing.
