Is it permissible for a man to marry a woman whose sister was breastfed with his brother's children?
Source: FtawySummary from Ftawy's records · added here Sep 2, 2026
There is no objection to a man marrying his wife's sister through fosterage, so long as they did not nurse from the same breast. It is permissible for his nephews to marry her sister, who was fostered with them, provided they did not nurse from her mother and there is no other impediment.
