[Al-Bukhari and Muslim]
Can the stepchildren marry each other?
My question is quite complicated so please read it carefully . One of my friend (ABC) father(FFF) died long back and so his mother(MMM) married another man(xyz) . Now this man(xyz) was also married before and his wife(RRR) died .(In short both MMM and XYZ are widow) This man(xyz) had one daughter(PQR) with his first wife(RRR) . Now my friend(ABC) is going to marry this girl (PQR) . Is this marrage valid or haram . J
