Is it permissible to marry the daughter of my sister's husband from her father's side, whom my sister breastfed?
Source: FtawySummary from Ftawy's records · added here Sep 2, 2026
If a girl is nursed by your father's sister five times before she reaches the age of two, your father's sister becomes her foster mother, and you become her foster maternal uncle. Therefore, she is unlawful for you (to marry), based on the Prophet's (peace and blessings of Allah be upon him) saying: "What is unlawful by lineage is unlawful by fosterage."
