Is it permissible for me to marry my sister's sister through fosterage?
Source: FtawySummary from Ftawy's records · added here Sep 2, 2026
Your foster sister is forbidden to you, based on the words of the Almighty: "And your foster sisters." Similarly, anyone who nursed from your mother—the one who breastfed you—is forbidden. Therefore, it is not permissible for you to marry anyone who nursed from your mother, even if she did not nurse from your [own] mother.
