Source: FtawySummary from Ftawy's records · added here Sep 2, 2026
It is forbidden for a man to combine two sisters in his marriage, whether they are full sisters or foster sisters, and whether they are free women or slave women, or one free and one a slave, due to the generality of Allah's saying: (And that you take [in marriage] two sisters simultaneously).
