Is it true that a man who was breastfed by his wife's mother is not permitted to marry her sister?
Source: FtawySummary from Ftawy's records · added here Sep 2, 2026
A husband's wish or regret about marrying another woman does not constitute a divorce, and his wife remains under his marital bond. A woman suckling her sister's husband does not make him forbidden to her sister, the wife. However, if the wife's mother suckles her daughter's husband, he becomes a brother to all her children. For suckling to establish prohibition, there must be five full sucklings before the age of two years.
